It comes from the shorthand of early telegraphers. R meant Yes I understand and W meant I will comply with your instructions. In the military phonetic alphabet R was Roger and W was Wilco. R currently Romeo but the British used Roger in World War 2.
R is a standard reply meaning 'Received' in Morse Code and flashing light communications.
Haven't heard Wilco being used for a W. W is Whiskey or William or sometimes even Washington. Wilco is military short hand for "Will Comply." In the Navy, the only person authorized to use Wilco is the Commanding Officer of the unit the order was sent to.
