If you have not already, you will want to look at SWIG
(http://www.swig.org/).  SWIG will generate C or C++ code from a
header file containing structs and classes and function
declarations.  That generated code can then be compiled and linked
to create a shared library (.so on Linux/UNIX or .dll on Windows),
which can then be loaded with the Python "import" statement.

It seems a bit of a stretch to me, but I suppose that could all be
done from within your application, perhaps by using os.system or
popen.popenx (x = 2,3, 4).  See 
http://docs.python.org/lib/module-popen2.html.

I'l let others on the list comment on whether this is dangerous.  I
suppose if all the code (that is compiled by SWIG) is under your
control or if you trust your users, it might not be too dangerous.
