That would be fine. The only thing that has to be special to run on 12 volts is the bulb. Everything else can be regular equipment found on 120 volt lamp fixtures. No special switches, wiring, sockets, etc. required. As long as the 12 volt bulb fits, you're good to go. Just be sure you get the polarity right -- easy to check with a cheap multimeter.
You could easily make one for less than $15 at the hardware store. Buy a socket, appropriate wire, cigarette plug (or use some other connector...there are much smaller ones), and something as a shade. A galvanized bucket, terracotta pot, or basket may look cool depending on your flavor.
