Is there a way I can make the following radio buttons?

------------------------
O 5 Gold ($5)
O 10 Gold ($9.50)
O 15 Gold ($14)
etc....

I also want the following thing:
HAve five gold the deafault and have it the price
Instead of having +/- the price, can i have x = price
Show the 5 gold price on the things, sincei ts deafault
