Thank you for your quick answer.

but with your code, I tried and saw something created in Hierarchy but i found some error message in console.

- My code:
      GameObject go = Resources.Load ("Prefabs/pf_main_pencil") as GameObject;
      UISprite sp1 = NGUITools.AddWidget<UISprite>(go);

- error message in console:

Setting the parent of a transform which resides in a prefab is disabled to prevent data corruption.
UnityEngine.Transform:set_parent(Transform)
NGUITools:AddChild(GameObject, Boolean) (at Assets/NGUI/Scripts/Internal/NGUITools.cs:371)
NGUITools:AddChild(GameObject) (at Assets/NGUI/Scripts/Internal/NGUITools.cs:356)
NGUITools:AddChild(GameObject) (at Assets/NGUI/Scripts/Internal/NGUITools.cs:752)

PS. I am using the latest NGUI version in Unity 4.2 , which I purchased two weeks ago.
NGUITools:AddWidget(GameObject) (at Assets/NGUI/Scripts/Internal/NGUITools.cs:777)

You must be new to Unity.

Resources.Load gives you a prefab. You can't modify this prefab. You have to instantiate it.

NGUITools.AddWidget adds a child widget to the target game object. You are attempting to add a child object to a prefab, and that's not something that's allowed.

You need to instantiate the prefab first before making any changes to it. Please consult the Unity's documentation regarding Resources.Load.
