Computer bot/automated system

I need a bot/automated system for a program. The things the bot needs to do: The program displays a row of colored pillars, of several heights. Every minute a new pillar of a random color appears, this color can change during the minute that follows after the appearance. When, for example, the pillar that appears is red, I need the bot to press a red button after a minute if the color of the pillar is still red. If the pillar changed to blue, then the bot needs to press the blue button. So better put: I want the bot to see which color the last pillar in a row of pillars is, a minute after it appears, and react to it by pressing the button of the same color and then repeat it. I hope I made it clear enough, for a programmer it's probably an easy task, but since I have zero knowledge in this sort of thing, it would take me forever.
