If you're having trouble figuring out how to use CGI from its documentation, start here in the Tutorials section. There are several pages that will help you get started with CGI. The most important parts of CGI are its parsing if incoming data, not the HTML generation stuff. My personal opinion is that generation is better handled with templates but CGI is indispensible for retrieving submitted data. For that, about all you need to know is $query->param("fieldname").

If you can access a real database, I'd recommend it over SDBM files. I think they're much easier to work with and are certainly more flexible.
