Major web frameworks like django, turbogears (thicker ones), pylons,
cherrypy (thinner ones) include all the functionality for doing this
sort of thing out of the box. If I were you I would go ahead and use
one of these frameworks and only start thinking about designing
something new if I hit a wall. Chances are you won't.
