Hi All,
I am looking to rapidly develop a commercial, cross platform (OsX/Win 7/XP/Maybe Ubuntu) product. The strategy I am considering is to rapidly prototype with python and QT then rewrite parts of my application in c++ as needed to get performance. I am new to QT but I have done plenty of c++/python(wxpython) before. Right now I have just been writing throw away test apps to get a feel for how QT works, before I purchase a commercial QT and PyQT icence I would like to solicit some opinions from other developers who have been down this route before. Any answers/feedback would be greatly appreciated:


-How mature is PyQT? Do many people use it in commercial applications? I would love to hear from some one who has used it to develop and ship a product.

-Has anyone used PySide, how does it compare to PyQT?

-In light of Nokia releasing PySide do people still feel its worth paying for a commercial PyQT license?

-Is their much of a performance hit from using PyQT?
