LightSwitch version one has already made this possible. LS/VS 2012 is a preview of the next version.
If you requirements are simple CRUD (Create, Read, Update, Delete) operations on tables of data, then you won't find anything easier (IMNSHO).
If your needs go beyond that forms-over-data type of scenario, just about anything
is possible, but the more complex your requirements are, the more you'll need to write some code.
Does that help?
