What is the best way to write a script? Mouse and keyboard interaction (clicks, and check for clicks)?

Question

Keyboard

What is better to use to write a program (script) that works for all windows, they are independent, work all the time, and perform approximately the following actions: after a button on the mouse has been pressed, it performs button presses on the keyboard. The question is, what is the best way to write? Can it be implemented in c++, for all windows?

Answer 1

See (global) mouse hooks, keystroke emulation, etc. (msdn google)
You can also use C++(C)
The question better means "more convenient". Any ready-made wrapper solution in any language. (If the task is described completely)
I will not prompt more precisely.
