USB as output

First of all, I am new to programming and Arduino alike. For my first project, I decided to build a throttle and rudder pedals for my computer. I'm using an Uno R3. How do I get it to output information to Windows via USB? (i.e, how do I code it to due so?)

How do I get it to output information to Windows via USB?

With great difficulty.

The normal Arduinos can only look like serial ports so you can pass information like that. The Leonardo and the Micro can also look like a keyboard or a mouse. There is no Arduino that can look like a generic USB HID game interface.
