Something like this maybe?

var gameMessageFont : Font;
var current : int = 0;
var questions : String[];

function Start ()
{
	GUI.skin.font = gameMessageFont;
	
	questions = ["Question 1", "Question 2"];
}

function OnGUI () 
{
	GUI.Label(Rect(0, 0, 850, 290), questions[current]);
	
	if(GUI.Button(Rect(160, 250, 150, 30), "To Question " + current.ToString())) 
	{
		current = current++ % questions.Length;
	}
}
