Alexander, you really do want to talk to sales at trolltech.com. There is (among
others) at least one thing Scott is overlooking, and that is the Qt
Commercial License agreement you will need for your closed source application
the very moment you start distributing it to somebody else.
This agreement covers code you develop with a Qt professional or enterprise
edition. it explicitly does not cover code that you developed with any of
Trolltech's free edition prior to purchasing a license, unless you make this
code available to the general public under the terms of the GNU GPL.
In other words: you may not have a GNU GPL problem, but you still may not be
able to release the software as closed source later.
If your problem is that you simply cannot afford the licenses today, talk to
sales at trolltech.com as well. They have a program for startup companies.
