Check out Microsoft Lightswitch. It's great for creating a basic CRUD front end application (web or fat-client).

Just point it to a database and off it goes - I created a front end to a system in about 5 minutes. It understands constraints and data types even to the point of placing pop up calenders where it encounters a date field.
