Rather than shamelessly repaste, I'd ask you to google for the Exeter chess club website and look up Dr.Dave's wonderful article on "choosing an opening repertoire" based on your style/preference of game.
What's a good opening to learn for my style

At your level, it's a waste of time to think of a playing style, you have weaknesses all over, and what you need to do is work on them. You should not start playing after your strengths (which quite frankly, doesn't really exist yet) at the expense of ignoring your weaknesses. It will stump your growth.
The most important value to me in the middle game is controlling the tempo of the game, and being on the attack, rather than the counter attack. I like keeping the pressure on the enemy, you know, offence is the best defence. I like semi open games preferably, but I'd try out open and closed games as well. What opening fits these values?
