public class ExampleClass : MonoBehaviour {
    private float rotAngle = 0;
    private Vector2 pivotPoint;
    void OnGUI() {
        pivotPoint = new Vector2(Screen.width / 2, Screen.height / 2);
        GUIUtility.RotateAroundPivot(rotAngle, pivotPoint);
        if (GUI.Button(new Rect(Screen.width / 2 - 25, Screen.height / 2 - 25, 50, 50), "Rotate"))
            rotAngle += 10;
        
    }
