Hello there,
I specialise in C/C++ on Windows; which is what most of windows is written in; and is ideally suited to your needs for this project.
But, C/C++ is not a scripting language; instead it is a powerful compiled language.
the C++ Win32 API supports enumerating thru running processes, and creating/deleting processes etc.
I'm certain I can do this for you, within a few days.
