You should start by purchasing a mouth guard, since if Javascript makes your teeth "cringe" then you're going to need it for every other kind of programming you attempt.

What I really mean by that is you're going to need a great deal of patience and perseverance to get good at any kind of programming, and even when you do get good at it, you're still going to end up battling things that have nothing to do with the programming language you choose (like browser compatibility issues, bugs that are other people's fault, bugs that are your fault that take you 7 hours to track down, etc.)

It's easy to enjoy things you are very good at, but to get there, you're also going to have to enjoy not being very good at all.

To answer your original question, if you are seeking to participate in an exciting new field, work on the tablet programming. If you want something where you can accomplish cool things with relatively few headaches, stick with Python but drop GAE and go with "normal" hosting.
