And, if moritz's answer is above your knowledge/experience level, please see Ovid's excellent CGI primer and a companion piece (for W32 folks), Setting up Perl/CGI with Windows, CGI Programming 101, japhy's CGI Tutorial Trailer, Tutorials for CGI.pm and using CGI, DBI and HTML::Template (a mini tutorial with example code) among others.

It might also be valuable to a perl newbee to read How do I post a question effectively? and the Monastery's PerlMonks FAQ.

In short, welcome to the Monastery.... and to its many resources, which include, as does the above, both on-site and off-site wisdom.
