Need simple autoclicker built. It must trigger when push notification is sent to my Gmail

I have a very simple project that involved writing an autoclicking app that clicks certain areas of my screen. It must autoclick on 4 different areas of the screen and all of these areas have different words. Now, here is the important part. it must ONLY click when I receive a push notification sent to my email which contains a few word combinations which I will specify. Nothing has to be fancy about this app as long as it works!
