You can use GUI.matrix for this, it will scale based on native dimensions something like this:

    var native_width : float = 1024;
    var native_height : float = 768;

function OnGUI () {
    
    var rx : float = Screen.width / native_width;
        var ry : float = Screen.height / native_height;
        GUI.matrix = Matrix4x4.TRS (Vector3(0, 0, 0), Quaternion.identity, Vector3 (rx, ry, 1)); 


///// gui stuff here

}
