Lyx - the first WYSIWYM document processor - has already a windows release using the non-commercial windows version of qt 2.3.

Angus Leeming and other Lyx-people managed to get a working lyx/win32 version compiler with Q... which can be found here

Lyx 1.3.7 with a newer Q... dll is also available: http://wiki.lyx.org/Windows/LyX137
