Yes, this is the correct approach to take although writing the extension 
module code by hand would be possible too.

Instead of making it a standalone extension module you can just link it 
into your application, and then after you've initialized Python you can 
just call the module's init function, and that will do the initial 
import.  As far as Python is concerned there will be no difference 
between that and a normal import.  SWIG will also generate a .py file 
that your other python code can import, so you just need to make sure 
that it can be found on the sys.path.
