Depends what you want out of it, but going down the web route would be the easiest option, I’d say.
HTML is very easy to learn. You probably know some already. If not, give yourself a few days and you’ll be reeling off web pages easily.
CSS is only marginally more difficult. But mastering it is something else, and quite satisfying. Very easy to play with.
But you might want to get straight to the number crunching. PHP programmer myself (so peraps a little biased 🙂 ). It’s open source, has a massive library of documentation online, and endless tutorials. And fully object oriented.
Combine it with MySQL for your databases and you’re good to go. Might seem like a lot at first. But once you’re all set up it’ll make sense.
That setup makes up a large portion of the internet.
