If you can use the Boost Python Library, you'll find excellent examples
of what you require at www.boost.org -- including creation, destruction,
and virtual methods.

If, for any reason, you can't or won't use Boost Python, then your
life may be a bit harder.  There are other C++ wrappers for the C
API's, but they may not be quite as simple to use -- I have no URL's
handy for their docs and examples.  With the bare C API, there is
no such thing as "a simple example of wrapping a simple C++ class":
you'll be re-doing manually the work that Boost Python (or other
C++/Python wrappers) implement for you.
