Is this by any chance "Terminal"? It's not really clear what you're
talking about here.

Sure, just like any other Unix. Apple even gives away all the necessary
tools. Sign up for a free developer account at
<http://developer.apple.com/>
and download them.

Err, sure it's possible. I would expect this task to be a decidedly
non-trivial one, but that doesn't mean it's impossible or that it hasn't
been done. If you're just starting to learn to write software, you'll
need to learn to crawl and walk before you can run with a complex
project.
