You dont need to set the keyboard up to act like a controller. Buy the PC version and follow the above steps. If you want to stick to a controller, buy a cheap Xbox360 Controller for windows and hook it up. Should install right away with no further prompts for you. Once that is set and the game is installed, log in like normal and in the character options menu just flip the switch from keyboard to controller and Voila! You now have cross hotbars. Ensure all the buttons are working correctly and start dragging and dropping your skills to the button you want them on. There are other options you can play around with as well to suit your needs.
