Newbie: connecting from windows to Linux: how-to?

I'm sure this question must have been asked before but I cannot find it
in the archives. If this is the wrong ML to ask please let me know.

I have PostgreSQL running on a Linux box and now I would like to build a
Java GUI tool to access/modify the data.

I'm guessing the first thing I need to learn how to do in Java is how to
connect from the windows machine to the Linux pg DB.

I've read http://jdbc.postgresql.org/doc.html about downloading and
installing the JDBC driver but I don't see any instructions relating on
how to do this in windows ...

Can someone explain to me or point me to a document that explains the
steps I need to take in order to establish a connection in Java from
windows to PostgreSQL running on a linux box?

Thanks!
