I found that everytime i deselect "QT core module" in the project-wizard 
i get a compile-error:
'QT_VERSION was not declared in this scope'. So i thought  it isn't 
possible to compile non-qt programs.
btw: is this correct behaviour?

If i understand you right, and i won't need the qt libraries on the 
target system then
there is nothing to be said against qmake.
In fact more build-options would just complicate the ui unnecessarily 
for guys like me.
It would just be nice to take the soucecode of any given project (wich 
have normally
standard makefiles i guess), edit and compile it.

Erm - ok, when it comes to  buildsystems I don't know the ropes.
(which is a reason more why i like QT-Creator :-)))
My testprogram won't link because of undefined references when i compile 
on windows.
that is because qmake obviously sets the QMAKE_LFLAGS = -l ws2_32 option 
in front
of the other arguments instead of after it (which is correct  - i think 
mingw has a bug here).
Therefore i cant compile on windows with QT-Creator, but have to do it 
on the command
shell by typing "gcc main.cpp -l ws2_32". (instead of "gcc -l ws2_32 
main.cpp" wich results
in the told undefined references)
