I don't think you can pack at arbitrary points directly, but you can
reorder children of a box with 

void	   gtk_box_reorder_child       (GtkBox	     *box,
					GtkWidget    *child,
					gint	      position);

as in the attached program.

I can't think of one...and I don't think there is...it would probably
cause all kinds of problems with the packing.
