hmmmmm... you'd need to implement some programming to interpret your control input to make it truly user-friendly. But it could be done! Radio Shack currently makes an omni bot you could use as a model.
of course, the omni wheels are sold by the pair and motors are only about 20 bucks. I highly recommend the investment :-)
Short answer is, depends on your application. Omni bots are feasible without them; for this one i removed the tires from some large size wheels I had lying around. It worked okay. I now have 4 omnis and they are an improvement (obviously) in this situation. If you put on a pair on the back of a 4wd robot it can make turning a whole lot easier also.
Keep in mind they come in 2 sizes... had I had some foresight I would have gotten the big ones; makes getting over doorjambs easier!

They occasionally pop up on eBay, or you can buy them along with all other Vex parts at vexlabs(dot)com.

it works better with four omni wheels.
omnis come in handy, i had a robot whose wheels were really spread out and it wouldn't turn without omnis. i uploaded a video of it
