It depends very much on what functionality you needed. If you needed a GUI for database CRUD operations (which is a lot of business processes and a lot of webapps now), then you could do that with nearly zero code, as the built-in behavior was all that you needed, but if you needed some interesting custom script and just a button "run it" and a textbox for results, then of course that would be nearly all your own code.
