Here is another question, are you deploying in Linux, Windows, Mac, or some combination of these? I think that may be a big factor to consider. I do like the look of Qt under Linux, however, I have never seen it under Windows. Qt seems to be very focused in Linux, with Mac and Windows support as a reluctant afterthought.
I have used wxPython and PythonCard under Windows and Linux. Under Windows, both of these are excellent, and allow you to do some very nice looking apps. I love the way PythonCard separates the interface code from the rest of the app functionality. PythonCard is a pleasure to use. It is not quite finished, but its developers are now in the final stretch towards the final 1.0 version. In Python, when you run into its speed limitations, you may have to resort to writing pure C. Similarly, when you run into a widget limitation in PythonCard, you may have to resort to pure wxPython code. In both cases, the advantages of using Python and PythonCard, will usualy make it worth living with their limitations. -Ruben -- http://mail.python.org/mailman/listinfo/python-list
