When I click on a button, I want another one to appear next to it with a message confirming the action.

Sorry, I’m just new to scripting and I don’t know how this works…
I created a button and the code is written below:

if (GUI.Button(Rect(520,340,150,40), "Quit Game") == true)
	{...}

Something like this:

private var showPopup = false;
private var popupButton = false;

function OnGUI() {
  if (GUI.Button(Rect(520,340,150,40), "Quit Game") {
    showPopup = true;
  }

  if (showPopup) {
    popupButton = GUI.Button(Rect(670,340,200,40), "Are you sure you want to quit?");
  }

  if (popupButton) {
    //Do quit operation(s)
    showPopup = false;
  }
}
