My understanding is that swat is no longer actively maintained.  Is there a GUI tool for maintaining Samba shares.
 Not only that I can't get it to work with xinetd on my system.
Webmin (http://www.webmin.com/) is a fantastic tool used for server management in general. It uses a web interface.
The samba component can add/remove/configure shares as well as change config settings all through a GUI.
