I'll just underline Mark's encouraging words, since you appear to be a 
little hesitant about diving in. I had to write a credit-card processor 
for a web application one of my clients wanted, and I found it was 
relatively easy to construct a Python COM server.

Although the application was in VBScript I created several test programs 
using VB, none of which had any problems manipulating the Python COM server.
