Well, yeah, squats are good for one part of the body, but make sure you do them correctly with proper posture because they can be very hard on the lower back otherwise. But the poster wants, I think, to tone the whole body, and so needs someone to propose a whole body program.
Squats are a good start. I have been doing the 30 day Butt Lift Challenge from BeFit on YouTube. You just need to do workouts the target the glute muscles. There are a ton of free workouts online.
That's a pretty broad post. Can you afford a personal trainer at a gym? That way you can tell them what you want and they can get you started. You'll only get "huge" legs if you do tons of leg resistance exercises (and if you have the genetic ability to get them without taking steroids, which is unlikely unless you have large legs to begin with).
