This would be a good project for any of the scripting languages (PHP,
Perl, Python, Ruby).  Since you're a beginner it might be best to look
at Python, as it's well-designed for people who are just starting
out.

Probably the simplest approach would be to write two programs, one
that does the database scan and posts new orders via XML; the other
would connect to the provider, get messages via XML and insert them
into the database.  Each one would do its thing until there was no
more work to do, and sleep for a small amount of time before checking
again.

Hope this helps you get started!
