I'll try to dig something out. I sent a broken example to the mailing
list a few days ago, but I'm sure I could put something else together.

You don't have to wrap the entire API or rewrite the whole application.
You just need to identify which classes need to be exposed to Python and
wrap those.

In terms of embedding Python into a C++ application (or framework), I was
never very happy about whether or not I'd got the reference counting
correct.

I'd advise against doing that unless there are strong reasons for using
either of those languages.

No problem. That's what the mailing list is for.
