As has been said above, you will need a web server if you plan to use CGI. But instead of writing one yourself, have a look at microweb. It is meant for running web sites off CDROMs, and hence is very small (although probably not small enough to run on a floppy). It has perl and CGI support built in and so it should work for you out of the box.

The only drawback is that it is shareware, but if you are writing this for a company, then software costs shouldn't be a big issue.
