I think you will have to parse the SOURCE files yourself.  After that is
done, there are several options including go-perl (from
http://www.geneontology.org), Bioperl (Bio::OntologyIO and relatives), and
GO-TermFinder (on CPAN).  I'm not sure which is going to be the best option
for you.  

If you are comfortable with RDBMs, you could download the tables from the GO
mysql database and do lookups yourself using DBI.

Hope this helps,
