    Yes.  If you want to implement a true interface (and it sounds like 
you do), you will need a typelib, and use the "win32com.universal" 
module.  Python can't help you create the typelib.

You would implement a method:

def spam(self, a, b):
   return "retval for c", b*a

Only "in" params are presented to Python, and the result is a tuple of 
(retval, out_args, ...)
