Use any controller with any PC game.
 

For those who have wanted to use a joypad with a game but the only controller supported are keyboards - try xpadder, it allow you you to use any controller with any game, no additional drivers, the application is a .exe file which does not require installing just load the app and configure your controller to match the default keyboard keys. xpadders a GUI - very easy to setup http://xpadder.com/
I've used xpadder with Goldslam and and I browser based text game, it works well.

There is also an app called Joy2key but I've not used this yet therefore I will not recommend it.
