Wheels are the easy part... there is a flange on one side of the hub with several holes to mount the disc.
Frame is the hard part... if your frame is not built for disc brake capilers, you can do 3 things- 1) forget putting discs on; 2) find frame adapters for the calipers (though this does not guarantee your frame can withstand the force); or 3) have bosses welded or brazed onto the frame to accept the calipers.
Discs aren't "all that" anyway.

If your bike came with V-brakes, your wheelset might not be compatible. Look for an extra flange on the left side of the hub with six holes to mount the disc to. If the flange isn't there, you're looking at a new wheelset (or at least a new hubst & rebuild).
Since disc brakes don't use the rim to brake, it doesn't really matter what rims you have. Disc specific rims, however, are lower profile and usually lighter.
You also want to make sure your frame and fork have disc tabs on the left side also, because without disc mounts on frame & fork you won't be able to mount the calipers.

Actually, the rim doens't play anything at all for disc brakes. What you need to see is if your hub is disc-brake compatible. On the bike non-drive side on the hubs you should see a place to put 6 bolts. Also, the spokes on your wheel must be 3-laced pattern. What that means, is that they're not radially straight from the hub to the rim, but sort of crossed.

look at the hub, where all the spokes are connected. most disc compatible hubs will have six holes centered around the axle for the mounting bolts for a disc rotor. more expensive hubs may have a large, splined shaft for Shimano CenterLock rotors. if you do have these caracteristics, make sure also that you fork has the mounts for a disc caliper (right near the axle, you'll see two holes for mounting) and also the same on the rear of the frame.

Your wheel ( hubset ) will be set up for a brake disk, it's either six or seven screw holes on the side of the hub and your frame or fork will have a mounting bracket for the brakes.

look at the hub; specifically, at what angle (vis a vis the other side) the spokes meet the hub. And the hub should have accomodations for the disc. The rim itself is compatible, but the wheelset is most likely not if you do not know it to be already.

if it is then on the left side of the wheel should have a disk mount in plain sight also check the suspention fork som of them come with both v and disc mounts
