Lakewood studios has a product iList Studio that looks really cool. In a few minutes of working with it however, it falls short. It is missing some critical features. The instructions tell users to use MySQL 4.0, what I didn't see is that this is a requirement because it can't authenticate with later versions of MySQL. Second I can't tell that it deals with relationships which takes away the real power of using a relational database.
It appears to be worth keeping an eye on though. Just not worth the steep price tag yet.
