What kind of coding language and other things to learn for a zelda-esque 2d rpg?

I want to work on a little summer project, and make my own 2d rpg, in a similar style to the original legend of zelda. Does anybody know what kind of coding language(s) i should learn, and other things i need for this? I want to include dialog, looting, shops, and possibly saving progress. It will pretty much be a dungeon-crawler, that works like the original legend of zelda. Thanks. :)
