(adsbygoogle = window.adsbygoogle || []).push({}); I want to build a gui that i can run on either a mac or windows machine. It needs to send keystrokes to a program, and i need to be able to set the program it sends to (maybe by process ID?). What would be the best language for me to do this in? Ive made one for windows using AutiIt but unfortunately thats only for windows.
