Easily? Not gonna be, most likely. Lots of good advice so far. Stick wih the compound exercises, don't waste time doing tricep kick backs and curls. If all you did were these exercises here, you'd be good to go: bench press, shoulder press, squat, deadlift, pull-ups/pulldowns, and a rowing exercise. They all work more than one muscle and there are ebough variations of them to cover all the bases.
Diet is an important part of the equation, like 70-80%. If you don't eat you don't grow. If you ask me, it's harder to bulk up from being skinny than it is to simply lose weight. You can lose weight with diet alone, but you aren't going to get big without busting your hump in the gym.
