That's the best texturing tool in the world, I've worked with loads others, and this one is the best, trust me

Apart from that, I'll make you a background, tell me what kind you like and I'll make it, be really descriptive, I'll make it down to the very last detail. It only takes me like 5 minutes max to make one, go me.

Whoopsie, just saw you wanted somehtign easy to use aswell. Well, I'll give you the same link. It has a 'witch' button that can let you make_okay_ textured background by just pushing a single button. Takes a few tries to get a decent one, but it's good for a start. Now if you really wanna make nice stuff, I'd suggest you read the tutorial that comes with the program. Oh, it also includes example textured background that the program made, but PPLLEEAASSEEE dont rip those!
