What's the problem? What have you tried? How has that failed? Have you designed your web interface yet? What about the flow of control? What kind of access controls do you have/want?

In other words, you have an idea of what you want, but I don't think you've really worked out how you're going to get there. Now, you may not know how to get there, and that's fine. But, I'm not going to write your code for you. A web script is a completely different beast than a commandline script, even if they share 90% of the same code.
