Game Logic - Run Something In Main Method When JButton Is Pressed

I want to run a few things in my main when a JButton is pressed but can't work out the best way to do it. Here's the code in the main.

public static void main(String[] args) throws FileNotFoundException, ParseException, InterruptedException{
Map m = new Map("defaultMap");
GameLogic g = new GameLogic("defaultMap");
GodsEyeView gev = new GodsEyeView(g, m);
gev.initialRun();

//Want to run this when a button is pressed.
HumanUser h = new HumanUser(g);
playerGUI gui = new playerGUI(h);
gui.run();
gev.run();
}
