For the grammatical subject you'd need to rely on configurational information in the tree. If the parse looks something like (TOP (S (NP ----) (VP ----))) then you can take the NP as the subject; often, though not at all always, that will be the case. However only some sentences will have this configuration; one can easily imagine structures with subjects that are not in that position -- passive constructions, for example.

You're probably better off using MaltParser though.
