If you prefer C, you can try SENNA: http://ml.nec-labs.com/senna/. It includes POS tagging, chunking, NER, constituency parsing and semantic role labeling. But dependency parsing is not there yet.
It's super fast (thanks to C) and very accurate (thanks to Deep Learning approach). The license is not for commercial usage though.

SENNA can be used with NLTK: http://pydoc.net/Python/nltk/2.0.2/nltk.tag.senna/
