I think the Hull book described a way to estimate alpha, beta for GARCH(1,1) using past data. If you need to do anything more than GARCH(1,1), you need a optimization package, e.g. levmar. You can also use Kalman filter to fit these parameters to option prices. But I have never done that though. Good luck!
