Perhaps learning Perl (not 'PERL') would be a useful first step. Then, realizing that CGI::Application is a module rather than an application (despite having the word in the name), and reading and understanding its documentation would start you in the right direction. Last, but perhaps in some ways most important, writing the necessary code and showing it here if and when you run into problems would be a really good approach.

The question you're asking is too broad to have a trivially easy answer.
