I'm not sure I understood your questions correctly, because you are basically describing the prefix project and calling it "a new idea" ?

Yeah, that's basically the description of gentoo-prefix.
Let me quote the first line of the prefix webpage: An effort to bring the virtues of Gentoo Linux to users on different operating systems, by means of installing in a "prefix".

Replace youtoo by emerge, and it's gentoo-prefix.

This is actually what gentoo-prefix does.

Us ?

bugs.gentoo.org, search for gentoo/alt prefix.

A couple hours max, following the bootstrap guide, depending on your hardware.

Great! Then please tell me, where I can download this emerge
installer, that installs me gedit on windows with a one liner.

I have missed the most important tool. ;-)

He wants to have a single prefix, or more realistically, a collection of prefixes for different platforms built from one platform with a single command. i.e. On my Mac I'd have several different prefixes, for brevity say:
/x86-macos
/amd64-macos
/ppc-macos
/linux-x86_64
/windows
etc.

Then I could issue a command like: "yootoo gedit" and it would emerge gedit (and all of the dependencies) into /x86-macos (what gentoo-prefix does now). Then it would emerge gedit (and all of the dependencies, which I'd guess are different for different host platforms) for each of the other prefixes (probably using a cross-compiler) so that the resulting binaries could be run on other systems.

Unless cross-compilers support in portage has improved since the last time I checked (admittedly, a couple of years ago) this is not trivial.

To come a step forward, I would highly suggest that you actually try
out Gentoo Prefix in the current form. After you have this pre-req
experience THEN see if your idea applies. To be blunt, you don't have to
"come up with an idea" for the Prefix team, you have to implement your
idea using the tools the Prefix team provides.

For a single platform, not too long (I [inspired by others] made a
script that builds a prefix on linux every night). Again, you need
experience with the project first.

So, since gcc-4.4 requires '>=sys-libs/glibc-2.8', how can I install gcc-4.4 with host glibc-2.4 ?

That comes much closer. But my approach was, not to cross-compile it
all. It's rather to compile directly on the target machines including
windows.

From the windows user point of view I want to come to a small setup
skript, that fetches all from the net, then compiles and runs it until
gedit pops up, in our example.

First it downloads a Posix environment, then a minimal Gentoo base
including a compiler. Than it can starts compiling using emerge and
prefix. By this cross-compilation would not be necessary for all, but
only for the minimal startup base.

I don't know the exact steps and time such a skript would need. Before
digging deeper into it, I wanted to know if it is possible at all and
if that kind of skript already exists.

You are absolutely right in this. That's why I am evaluating the usage
of gentoo and emerge during the last days. My next step will be to try
Prefix. Then I will have a deeper insight.

As I wrote, I don't want to come up with a new idea, I rather expect
that this vision is already around. I simply want to know, how far it
is implemented. It seems it isn't.

So I have to consider to implement it myself. But before I need to ask
myself it it is realistic to reach that target.

That sounds good. For my original target it is necessary that you can
do it in standard windows environment, to reach a maximal base of
users. Hence the question if there a positive reports, to setup prefix
with Cygwin without the need an enterprise windows.

Isn't that why people use a prefix at all? To install different
implementations or versions of something on the same machine?

I probably should have used a more windows like syntax, to indicate
that i don't mean to reinvent emerge, but rather an installer that
installs me a basical gentoo environemnt on any platform.

It's not that I am frightend of sources. I simply need that as a
prerequest for the tool a am working on.

For sure I could code that into my tool itself. But the unix way is to
separate different tasks into different tools and than let them work
together.
