Thanks for that!

I didn't mean to confuse the term backend, but since it's not a cgi app that is going to be web accessable I considered it a backend app.

That said, all this app is going to do is grab encrypted e-mails from the mail server, decode them locally, and print up receipts/mailing labels. And if I had users that were more computer savvy, I would be doing this in Tk in a heartbeat. But given that the person using has probably had about 5-10 hours total computer experience, I figured that the browser interface would be preferable.
