RBrul, written by Dr Daniel Johnson, is a nice stepping stone between something like Goldvarb or SPSS and R. The interface is easier to use and it was designed by linguists for use on linguistic data. It was the advantage over Goldvarb in that it can produce Mixed Effects Models (because it is using R) and it can also handle continuous as well as categorical and binary variables.
