The first release was November 1998 for Qt v1.41.

Yes. This is a function of Python rather than PyQt.

Yes.

The bindings are very thin. The main PyQt module is a 3M DLL on Windows. Costs 
have never been measured because AFAIK they have never been an issue.

You generate your own extension module using SIP. Alternatively, ActiveX 
support is planned for the version after next.

Not that I'm aware of. You can do 99% of what you can do in C++ in Python - 
but with fewer lines of code and much less programmer time.

Can't comment on that.
