telcomwork,
either you do that on a phone or you do that on a pc. or alternatively you can set up a wallboard or something like that. we used a plasma tv with an attached computer running cms supervisor as a wallboard with great success. pretty nice, good visibility and price much lower than of a hardware wallboard.
using a phone you're not only limited with physical phone buttons, be aware that numerous vu-stats buttons place a significant load on a system. it is not recommended to use numerous vu-stats buttons with refresh intervals shorter than 30 seconds.
by the way, if you have a recent enough call center you may have ip agent shared control licenses for all of your cc elite agents. check your disp sys cust page before last, "maximum ip registrations by product id" table for AgentSC product id. if you have it, you may request or purchase ip agent software cd and use it. shared control means that ip agent won't allow an agent to work in roadwarrior or telecommuter mode, only in "control a phone via server" mode. which is more than enough to have a softphone and to display vustats on a pc.
