But What to Design?

I designed a CGI program that would do the following things:

Query the Port Authority web page (using the sockets API) and download the outgoing schedules (in HTML) for all the busses that can bring me home from school.
From the results, parse out the times for the stop at Forbes and Bigalow (where I get on the bus).
Find the next time the bus will be arriving and return those times to a browser.

The program runs on Windows NT Personal Web Server in my office.
