Cons
Con Similar to PyQt, you need a C++ background. at least you can read C++ code
Qt's document is poor, and Qt for Python(PySdie) is even worse. this document assumes that you are already familiar with Qt. if you want to customize a Widget, you need to look at the Qt C++ source code to know what to do.
Con Community is still very small
