If it's flat, you can lay good money down that it's punctured. They don't go flat without a hole in there somewhere.
You don't need to buy a new tyre, but at the very least you'll need to fix the tube. Follow (to the letter) the instructions on a puncture repair kit. I say "to the letter", because most people fail to let the glue dry before applying the patch, causing the repair to fail.
You'll need to buy a pump to suit your tubes' valve. Most pumps have the ability to fit on either style of valve. I love my Topeak Road Morph pump, but it's not the cheapest one out there. (Perversely, by spending so much on a pump, you're guaranteed to not get another puncture whenever you carry it .... )
Carry a spare tube from now on, since it's easier to fit that on the road than to patch your tube. However, you should still carry a kit with you because you may get more than one puncture on a ride.
(PS - look for the cause of the puncture inside the tyre before you put the tube back in there. One little prick can ruin your day more than once!)
Music was better when ugly people were allowed to make it ....

Qs: my wheels are shimano R500. How fragile are they?
R500 are fine.
Victor, its quite easy to fix flats once you are use to doing it, however it can be quite difficult the first couple of times. So I'd recommend that you have a couple of practices at home.

Replace the inner tube, or patch up leaking one.
Chances are you probably had a pinched tube.
I used to have a set of R500, never had any problems with them. As with all new factory wheels, get the shop to inspect them after a couple of rides on them.
Punctures are part of cycling,
