i think you would be better with a 3D text so you can place it in the position of the screen. For the buttons i would suggest using Physics.Raycast so you can get what object the user hits ad use that in your programming. More info on this can be found here :-

for example

var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
var hit : RaycastHit;
if (Physics.Raycast (ray, hit, 100)) 
{
    if(hit.gameObject.name == "button 1")
    {
        Debug.Log("Hit button 1");
    }
}
