Client Only Installation On Windows XP

I am new to PostgreSQL.  I downloaded and installed the server software 8.1.4 onto a Windows XP machine without any problems.  I am able to login create db's and even able to import existing data into new dabases.  I have yet to figure out how to install client software on a workstation running Windows XP.  Is there a simple install program, similar to the install program included with the download for the server software, that I can use to setup workstations running XP  so they can login to the server on the same ethernet network?  Right now I can only access psql from my server machine.  If no such install program exist, is there any plain english documentation explaining this process for Window XP machines?
