I want to be a dj and need help?

Im 17 and want to start getting in to dj'ing, but i need help. By Dj'ing i mean like making music on computers,i think its called a virtual dj. I mean i know this sounds weird but i know what music people like to listen to when they're out and stuff, but i want to make my own music. I love the likes of guetta. I downloaded the fruitloop demo but it seems a bit to difficult for a beginner, any help please?
