Maybe declerative programming could help with that, like prolog/datalog. I don't think you can go much higher than inputting only the rules and data of your app, the only thing more higher than that I could imagine is an AI that could create a program written in a declerative language with only a subset of the rules, figuring out the rest by itself - which is pretty much what developers do
