Sourcecodes needed

Hi,

I have to write a Installationprogramm for Windows Applications, based on a
simple scriptlanguage. But i never programmed in Windows. Could anybody tell
me where to find some sourcecodes which helps me to learn the basic things ?
Or did anybody before wrote such a programm ?
