I agree with your three problems, but only if problems means hard roadblocks to achieving your goal.
Much of programming is encoding what you want to computer to achieve and is therefore a rather long process, but not necessarily hard. Precisely specifying how a GUI should look has a substantial amount of necessary complexity, and writing that out doesn't fall into 1, 2 or 3.
You could also argue that that is a separate thing from programming. I don't at all mean to be to be snobbish here, just that it's useful to draw the line somewhere between there. Modeling is not programming. Architecture is not really, either, even if the process can involve programming.
