except for the possibilities to put lisp evaluations in this code,
you are getting dangerously close to GLE's tree dump formats.

test snippet:
      (GtkHBox "Window.VBox.VBox.Button.HBox"
        (generic-gle-name)
        (arg "GtkContainer::border_width" 2)
        (arg "GtkWidget::visible" true)
        (GtkLabel "Window.VBox.VBox.Button.HBox.Label"
          (generic-gle-name)
          (arg "GtkLabel::label" "Pixmap\ntest")
          (arg "GtkWidget::visible" true)
          (child-arg "GtkBox::position" 1))
        (GtkPixmap "Window.VBox.VBox.Button.HBox.Pixmap"
          (generic-gle-name)
          (arg "GtkWidget::visible" true)))

hm, i can tell you, you'll need slightly more logic for such
a "function"! ;)
