Web interface to script?

I have a perl script sitting in svn repos, associated with many web
development projects at my work. The script scoops the repo revision
# and dumps it into a .txt that developers then print out to their
pages to ensure version compatiblity (for me in qa, i can see what
version im looking at and tell quickly what is a new bug and what's
been fixed, etc..) It was recently requested that I add a 'web based
interface' to my script(s, we are currently working on 20+ projects)
to basically have a 'button that runs the script before the developers
update their local repo'.
Im not a super perl hacker, and dont know cgi very well, is there any
pointers you can give me on how to accomplish this (or even better, a
script that updates on checkout)?
Thanks!
