You should take a look at PythonQt. From the homepage:
PythonQt is a dynamic Python
(http://www.python.org) binding for Qt
(http://www.qtsoftware.com). It offers
an easy way to embed the Python
scripting language into your Qt
applications. It makes heavy use of
the QMetaObject system and thus
requires Qt4.x. In contrast to PyQt ,
PythonQt is not a complete Python
wrapper around the complete Qt
functionality. So if you are looking
for a way to write complete
applications in Python using the Qt
GUI, you should use PyQt.
If you are looking for a simple way to
embed Python objects into your C++/Qt
Application and to script parts of
your application via Python, PythonQt
is the way to go!
