Writing a script in Python is probably your best bet. Start here:

The best is to start reading the beginner's tutorial of python on python.org and the examples on the GRASS-Wiki page.

The easiest to try out python is to go to the GRASS command line and to launch Python there. You can then try out python code in real-time before putting it all into a text file and launching it as a script.

That depends on how you install GRASS. If you use the MS Windows standalone installer, yes.
