Setting the expand property on the buttons will have no affect on
how the GtkVBox allocates space. You'd have to set the property on
the immediate child of the GtkVBox.

(Note that 'expand' is actually a "child property". The set of 
"child properties" on a widget depends on what container it is packed
into, not what the type of the widget is.)
