Making An Arcade fightstick for PC

at the bare bones of this, this will be my first time ever working with a arduino or any kind of coding/electronic device of this sort. I just needed some help on making my own arcade fight stick (this) without a joystick and with a bit less than 20 buttons. I was wondering if you guys could help me out on what I might need. here are the buttons I'm going to be using: Black Rim Sanwa OBSF 30 Pushbuttons thanks
