I have an PGImage in the Background and added three PGButtons like this:
  AddWidget(new PG_Image(NULL,p, "menu.png"));

  AddWidget(new PG_Button(NULL, MN_SINGLEPLAYER,
 PG_Rect(50,300,247,99),"","localgame")); AddWidget(new PG_Button(NULL,
 MN_MULTIPLAYER, PG_Rect(400,130,303,99),"","networkgame")); AddWidget(new
 PG_Button(NULL, MN_QUIT, PG_Rect(332,450,137,99), "","quit"));

Here is are the three sections out of my theme:
    <widget>

        <object>
