Python is the most used tool for Natural Language processing and the community of academics who built and use the NLTK have probably already made a tool that will do most of what you need.

It is best to start out with a tutorial like this one, http://www.desilinguist.org/pdf/crossroads.pdf and work with a simple European language. Then when you are more familiar with the tools, start working with Arabic texts.
