Answer 1

I have a program that detects when certain machines are online and creates a button with a green "online" icon to show this.

Use a JToggleButton instead, as shown here¹ & here².

I can't figure out a way to do it once the button has already been displayed.

To toggle the state and fire an action event doClick() or alternately setSelected(boolean).
