Its VERY difficult to play Guitar Hero with only the Wii controller. I highly recommend getting the guitar, too. And if you're going to start with Guitar Hero 3, dont pay more than about $5 for it without the guitar. That game is pretty old. There have been about five more Guitar Hero games since GH:3 game out. I have Guitar Hero: World Tour, Guitar Hero: Metallica, and Guitar Hero: Smash Hits and I can recommend all of them.
