Excuse me butting in, but this is redundant information:
  // b belongs to w
  button b = w.spawn("button");
  // b belongs to w
  w.contain(b);

It seems to me that you're trying to fit two concepts into one box, 
the widget and its properties. All this jumping through hoops occurs 
because you're trying to manipulate a "widget that must belong to a 
window" when in actual fact you're interested only in its properties:

  button_properties bp;
  bp.label("Click me");
  bp.size(10,10);
  bp.foreground_color(red);

  window w;
  w.add_widget(bp);

Persumably, therefore, the button_widget's constructor would be
  struct button_widget {
    button_widget(window const &, button_properties const &);
  };
