I think all you want to really do is dynamically generate a mapfile  
based on the thematic classification you want to apply to the  
polygons (we have to use SQL Server in a similar manner, and that's  
how we do it.)

Look at the MapServer Website under classes and look for an example  
maybe with a regex (to identify the field in the dbf that matches  
your database).

We use either perl or php to either replace placeholders in a  
template file for cgi applications, or (using mapscript) write the  
mapfile from scratch.

If you are still having trouble this is probably a better question to  
direct at the MapServer users list, as it sounds as though you have  
ms4w working OK.
