use JavaFX if you want

[yoyonerd]

the game maplestory was coded in c++

but that'll take you a while to get c++ down, then learn direct x

if this isn't like a big thing, and just a small personal project

try c# with xna, you need like NO prior knowledge, and the people who made xna, even have their own video tutorials, thats right VIDEO tutorials right on their website, the vids supply the resources and everything, and there's two sections, one for 2d games and one for 3d games

using the xna framework, you can develop games for windows pcs, xbox live downloadable games, and even microsoft zune games

and its all really simple, perfect for just the once in a while type of thing

Use C++, there are a lot of DirectX tutorials for C++.

Depends how simple you want it.. You technically could use VB and pass it off as a game, but it's be pretty shitty. C++?
