You need to do some homework. QTP AOM (Automation object model) can be used to do automation of QTP itself, from within a vbScript. Look at QTP Automation Reference for more help on this capability.
You will also get tons of hits if you search this forum with the single keyword, "AOM", as this question has been asked answered many, many times in the past.
