easy way:
1 - compile as normal
2 - after qmake finishes, COPY cygwin1.dll mingwm10.dll and qtui.dll (or
someshizzat like that) to the OUTPUT directory of your build. now you can
run all this from just doulble clicking it in Windows.

It probably depends on what you're actually trying to do/build.  I use
Cygwin as my environment to build VLC (a cross-platform video package).  VLC
is adding a QT4-based GUI.  The output file set (a lot of DLLs, plus the
main executable) does not require any Cygwin or Mingw DLL to run.
