Just a tip, but there are tools that make what you want very easy to do by just running a few commands on the command line. For what you are trying to do, there is a tool called Gantry that is awesome:
Of course, you have to learn how to use that tool also, and in the long run, developing an app by yourself is going to be a good learning experience. But if you are trying to just get this up and running quickly, investing some time in learning something like gantry is going to be valuable.
So some google searches on "perl CRUD" and you'll find some tools that will make quick work of putting a web frontend on your database (CRUD stands for Create, Retrieve, Update, Delete).
