theshrike79 was talking about automating. Automating using an UI requires you to have a program which can simulate click events and a Display server which allows this. It's also really brittle, because you are not actually depending on the action you want to invoke, but on the UI location this action is exposed at. Automating terminal commands is easy, because that is how the OS works anyways. All programs invoke each other by issuing (arrays of) strings to the OS and telling it to exec this.
