The OP listed the following requirements: "simple CRUD app" That is more than sufficient to pick a framework/database and start working. I'm not sure how many simple CRUD apps you have built, but the challenge tends to come when you put them in front of users who can't figure out the interface. Consequently, I'd argue to choose a framework quickly and get it in front of a user as fast as you can.
