Go for it. 9 years ago when I was your age I messed around with batch scripts and had tons of fun though I didn't make much useful things. Anyway I think it laid the ground for the future education in programming I would undertake. It's never to early to begin. I don't know anything about this small basic but I suggest you get started with C++ right away, it's a powerful language once you get the hang of it.
I'd say it isn't too hard to learn to do specific tasks. Most with some knowledge in C++ and a bit of help from bases or people can whip up a hack. The hard thing is to be creative and come up with new ways of doing things on your own, that's something that takes tons of experience. I have studied programming languages for years and yet compared with a lot of people on here I don't really know shit.
