Thanks for the reply, Mark.

While I would not discount the possibility of supporting something like
PythonQt, this is not a case where I have the option to select a
different Qt/Python combo.  This is a customer mandate, so I need to
specifically support PyQt.

I already have Python bound to my Qt application via SWIG.  I am
specifically concerned about how to integrate PyQt into that arrangement
so it can function at the same time as my main thread's GUI without ugly
event delays.
