I'd recommend C++, I mastered it within a few hours. Why? Because it's pretty much the same as PHP/JS. So if you're interested in learning website languages as well, use C++ / PHP / JS since they use the same syntex so it's easy to learn the others once you've learnt just one of them.

(I've not tried learning C# so i can't recommend it nor can I not recommend it... VB I found hard because it's syntex was very different too what I'm used to )
