I don't know of any easy way to do it.  The hard way to do it would be to
write an extension module that wraps your DLL function(s).  If you don't
know how to do this, read about "Extending Python".  If you don't know
C or C++, I'm afraid you are probably out of luck until someone implements
a generic solution....

Here's an interesting project for Windows programmers: Write a general
purpose DLL caller.  Functions should be declared in python (like in VB)
and the DLL should be accessible from python without requiring the user
to write any C code.  This is doable (VB does it).  The hard part will be
converting the DLL function arguments.
