I wouldn't recommend autoit. Instead, try Python. Python has everything that autoit doesn't: a fast interpreter, cross-platform support, and a much more readable syntax. If you need to make executables, there's pyinstaller or py2exe. Python is also object-oriented in some ways. Not to mention that there are pyglet, pygame and pyaudiogame if you want to do games.

“There are four things that we ought to do with the Word of God – admit it as the Word of God, commit it to our hearts and minds, submit to it, and transmit it to the world.” — William Wilberforce
