AFAIK, nobody is developing Qt bindings extension. The problem is that
if you can't use Qt to develop and distribute non-GPL application
without paying a commercial Qt license fee.

When you posted your message to the public I assumed that you were
interested in attracting other people to help or use your extension.

What I am trying to tell you is that because of the license fee payment
requirement, Qt is not interesting to many people.

Either GTK, Qt and wxWindows can work either on Linux and Windows, so
that is not a problem.

I suggested the wxWindows library as an alternative because it is
practically as powerful as Qt and is LGPL, so everybody can use it
without paying commercial license fees. Therefore, a wxWindows extension
would be more interesting than a Qt extension. See what I mean?

Because of the license problems, unlike a Qt extension, a wxWindows
extension would be acceptable for in PECL. If you get your extension
accepted in PECL, you can get much more exposure to your work and
eventually more users and other people helping in the development.
