CodeJunkie,
I'm kind of needing this too and I've been working on it in my spare time to update a site for work... unfortunatly there doesn't seem to be anything out there really that is much help for this specific problem.

I'm going to stay away from code that generates the pages. The problem with that approach is that it still creates a mess especially in my experience working with people who thought they could simply update the HTML pages which of course got everything out of sync. :) YMMV however if you are working on it on your own or with people that understand they need to use the update tool.

I'm planning on using MySQL and building it like a normal web app, using CGI, HTML::Template and possibly CGI::Application, etc. My suggestion is use a templating system and make it modular. I'll share my stuff but at the moment there isn't a whole lot to share (and actually I may have to write it in PHP since my boss thinks its the best ever .. or something ...gotta love those PHBs!)
