scale/position gui.button on every res (android)

I have a gui.button, and i would like to resize it and position it same spot in every device, this is my texture

var Pause : Texture2D;
function OnGUI(){
	GUI.backgroundColor = Color.clear;
	 if (GUI.Button(Rect(60,10,50,50),Pause)){
	 Debug.Log("Button was clicked");

If this is possible for you, I suggest looking at unity’s new UI system (4.6+), it makes this really simple tutorial here
