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.
