does Cisco provide a gui tool to monitor bandwidth and such, I've read about netflow but I can't seem to find the program I do however find other GUI programs that show netflow information like NetFlow Analyzer Integration.
let me know
not Cisco product, but you might want to check out Netflow Tracker from Fluke http://www.flukenetworks.com (previously Crannog in Ireland).
if you really want to sink your teeth into something, check out ACE & ITG from Opnet - http://www.opnet.com - which also can eat netflow data either taken from cflowd/flowscan ( http://www.caida.org/tools ), or through their VNE consolidator.
if your needs are simpler, then Scrutinizer might be for you: www.plixer.com
