I think that's true in both respects.  Basically, the Qt license just covers 
the development of the application, not the usage.  If you develop under 
Qt3.x GPL X11 and someone compiles the application for Windows under a 
commercial license and you are allowed to distribute the windows version as 
well as the GPL version.  You will see offers to compile under Windows from 
time to time on the qt mailing list and the trolltech employees who frequent 
the mailing list appear to have endorsed it as acceptable.
