My understanding is that you can use the gratis version of Qt for
Windows - you can package your Python source, the PyQt binaries, the
Qt dll and perhaps Python itself in one big package and distribute it.
You can't distribute just Python bytecode; you must also make available
the Python source. You don't need to include either the Qt or the PyQt
source. You cannot use your app in a commercial setting yourself, but
people who download it can.  --
