You can use yum to install samba-swat. The configuration is pretty simple.
Edit /etc/xinetd.d/swat (below given is mine. Modify 'only_from' to match your subnet and 'disable = no')
# default: off
# description: SWAT is the Samba Web Admin Tool. Use swat \
# to configure your Samba server. To use SWAT, \
# connect to port 901 with your favorite web browser.
port = 901
socket_type = stream
wait = no
only_from = 127.0.0.1 192.168.0.0/24
user = root
server = /usr/sbin/swat
log_on_failure += USERID
disable = no
save the file and start the service -
# /etc/init.d/swat start
make swat persistent across reboots -
# chkconfig swat on
and that's it. You can access swat by http://ipaddress:901
Also make sure to open the required port if you run a firewall.
