I can't answer that definatively.  I know KDE is (being?) ported to 
Windows, but I guess they manage to do that as free software (i.e., 
under the GPL license of Qt).  It seems to me I've heard of some 
commercial programs using (or planning to use) Qt, but I can't recite 
any names.

Yup, and, iirc, the original terms of Qt's dual license required that 
you make a decision up front--if you were going to develop a commercial 
application under the commercial (not GPL) license, you had to decide 
when you started developing your application, and from that point, pay 
for Qt.  (If that was not for Qt, it was for some other dual licensed  
library.)
