..."create an interface for a website, to allow content management"... "Being a novice to perl"...
I've built several interfaces along the lines you have described and here is the best advice I can give you on the subject. The difficult part is error trapping, building a CMS is pretty easy* if you don't care about input from the lusers that use the system.

horizontal scrolling (and possible janitor
