It is true that the QT library is very huge, but it offers a whole programming universe. QT is now freely availabe for Mac OS X to if the app is releases under the terms of the GPL. In addition QT is available for embedded linux too. It exists an older version for non-commercial, open source apps under win32 (no QT source).
Another advantage is that QT is developed very fast, for example QT has unicode support since 1999, other toolkits like GTK+ required more time (AFAIK since 2002 has GTK+ unicode support too).
The meta object compiler provides a C++ extension called signal and slot mechanism, which is typesafe. You can write each software component (classs) for its own and connect them without knowing each other.
Last but not least QT is developed by a business oriented company, but this doesn't matter because Trolltech needs money in order to develop such a great toolkit.

If someone backport it to QT 2.3, which is also available on Win32 (non-commercial), can it then be used for GPL apps on Windows?
I am interested on an free port to windows since I have developed an QScintilla based app (CUTE) on linux, which i like to port to win32.
