If you don't need it to be on the web, Python + Sqlite isn't too bad. Then a GUI like pyqt could do the trick (with UI designed in Qt designer). It still requires some coding, though.

If you need it to be on the web, php + Mysql is probably one of the easiest to learn. The cool kids might have moved to something else, like node or django, though. It also requires learning done basic HTML, but the complexity is reasonable.

I've dabbled a bit in Python here and there and indeed I feel this is most likely the route I will take, before web (as this is not a requirement for me as of now).
