Lots of people use the Ardiuno to do this (then you can use the Arduino IDE and simplified C commands), or you can use a USB based programmer. I do not have an Ardiuno and don...

Upload the code to an attiny45, put a 20" or so wire on pin 6 and power with 5v.  You'll need to put your radio clock close to pick up the signal best. ...
