Although you did not specify what the specifics of the programm are, I think the easiest way is programming it yourself. You are new to LabVIEW but it is the fastest way of learning by doing it. You can access the pulse pattern.vi (analyse-signal processing) and connect pulse specifications to it (through indicators). If you need a pulse train, simply put it in a loop and use the shift registers to add each loop process to the signal.
