: But if (as was stated before) only the X11 codebase is available under
: GPL, then the fact that the license doesn't specify an OS is a technical 
: detail.  In order to run the GPL version under Windows, you would essentially
: be emulating Unix on Windows (cygwin + X-server), with all the little
: gotchas that tend to come with emulation.  Of course, if the X11 
: source is GPL, then you could, in theory, port that to Win32 yourself.... 

The licensing for non-commercial applications for Qt/Win32 was changed 
very recently. Have a look here :
