How to do Unity GUi Buttons?

Say I created a GUI Button in Unity, it gets that default unity look, so then I put a texture over it, now its that default look with a texture over it. But how do I get rid of the default look? I want just my texture to be used instead of seeing the GUI Button I only want them to see my texture, How do I do this?

GUI.Button (new Rect(25, Screen.height/2, 160, 45), MainMenuIcons[0] );

Use a GUISkin or at least a GUIStyle.
