I found an absolutely awesome application called
slGrid. It was recently bought by
Senza Limiti, a technology consulting company based in Slovakia. They've since made slGrid an open-source application, which is very cool. It uses AJAX and PHP to provide an interface for creating grids by loading content directly from a database. You specify the table and fields, and it takes care of the rest. Check out the
slGrid demo to get a better idea of what it does.

Using slGrid is literally as easy as this:
[php]
Fatal error: Call to a member function SetDatabaseConnection() on a non-object in
