Customizing GUI buttons

Hey fellas.Ive finished a simple End-of-level script with GUI options : restart,continue,main menu.And the problem is that it displays only 2 of them.And there are restart,continue on the same spot.How can i customize it to display everyone and make it bigger?Or even add a text above it like “You have just finished level”,or putting it in the middle than just upper left corner?
Thanks

You should read this: http://docs.unity3d.com/Documentation/Components/gui-Basics.html

Also to change the style I would use a GUI style,
here’s the code:

    //Java script:
    
    var style : GUIStyle;
    
    //then at the end of your GUI just put
    , style);


it would look like this:

function OnGUI() {
GUI.Box (new Rect (0,0,100,50), "Test", style);
}

basically the same in C#
