It depends on how "Qt-ish" the myth API is. If plugins want to take
advantage of the Qt API (either explicitly, or implicitly because the myth
API sub-classes from Qt classes) then it's not a good idea because you
have have to use SWIG to wrap Qt as well. On the other hand, if the myth
API doesn't expose Qt then it's more practical.

PyQt is build using SIP
(http://www.river-bank.demon.co.uk/docs/sip/sipref.html) which makes it
easy to define new Python modules that extend existing ones (like PyQt).
PyQt doesn't use SWIG because (historically) the C++ support has been less
than ideal.
