[Catalyst] Web-based SQL query builder

[snowjack at fastmail.fm]

I have a database of small-med complexity (15 tables) and would like to
write a web app that will allow users to query the database any way they
like, changing sort-by parameters, date ranges, any combination of
tables, etc. I'm wondering how others would approach a project like
this. What tools would you use? 

Thanks!
