I think it has discussed in forums and such (see KDE's forum, for example).

The answer should be: that text is a bit controversial, but, *as long as 
Qt/win32 is GPL* (as the X11 version has been since a long time) you can 
use it as a GPL library.

If you don't want to (or can't) use GPL for your program, you need to 
buy the license, but this is not the case for Xastir I think :)

It's tricky, but you missed the sense of that sentence:
you _may_ charge money for providing the software. you must _not_ charge 
money if someone else (who got the software from you) gives a copy of 
the software to a friend.
i.e. you cannot demand compensation for re-distribution.

You cannot prevent other people from doing the same as you - charging 
for the software for a fee.
Licensing stuff is more complicated than programming :)

Exact :) I agree! As long as Qt has a GPL license... you can do it.

Thank you
