Your question sounds like someone in their first woodwork class who's been handed a log, been given access to every tool in the shop, and wants to build a cuckoo clock. :)

OK, I'm exagerrating, but understand that Perl is a tool which will allow you to build absolutely anything you want, but that skill is required to produce beautiful results.

You need to use Perl to build a CGI user database? The people here can definitely help you, but you're going to have to be prepared to do the programming yourself.

Tutorials have been referenced - you need to read through these, try them out, and come back with specific questions on the parts where you would like clarification, or the parts where you get stuck in your programming.

There are articles on perlmonks which describe the best way to ask a question, but they boil down to: a) have a definite question that you answered, b) demonstrate that you've attempted to solve the problem yourself before asking for help (e.g. supply parts of your code which don't quite work!).

Welcome to perl CGI, where writing documents meets computer programming, and the skills learned in doing so can change a "user" into a "guru". ;)
