or dive right in cgi-app / mojo / dancer / catalyst to start writing perl web apps

Yup, this is a very basic question indeed.   Yes, it is a n00b question, but, that’s just as good a place to begin as any other, so let’s get started.

The name of this game is to figure out how to get a job done while “actually having to figure out” as little as possible.   Well, to understand anything of what any of these tool-makers are saying, naturally you have to understand what they are saying ... so begin, as suggested, by learning how HTML form-processing actually works.   POST/GET, <form> tags, maybe what AJAX is, and so on.   “Speaking the local language, well enough to find the bathroom anyway,” so to speak.   Set your immediate objective aside for a bit; you’ll get to it in a moment, but not yet.   Next, since you are using Perl, proceed by learning about some of the existing Perl packages that are specifically designed for you.   There are literally thousands of them; too many to list.   But one or more of them are absolutely certain to solve either all of, or a very useful part of, what you are setting out to do.   Your goal is to minimize ... as much as possible, to utterly eliminate ... the amount of “original coding” that you need to do, in order to accomplish this decidedly un-original requirement as quickly as possible.

Actum Ne Agas:   Do Not Do A Thing Already Done.

Just because there’s a Hall of Mirrors in front of you, it does not mean that you have to stumble through it, to get where you are going.   Instead, look for the very bright trails that were purposely left behind for you by the preceding passers-by.

The answer is:   Yes.
The question is:   “Hasn’t somebody else already done that?”
