I think you are looking for Gtk::Container#add, and not  
Gtk::Bin#add\_child.

(pseudo code, not tested)

align = Gtk::Alignment.new(0, 0, 1, 1)  
b1 = Gtk::Button.new(“Test”)  
b2 = Gtk::Button.new(“Test”)  
align.add(b1)  
align \<\< b2

After reading closer the Gtk::Alignment doc, you can only pack one  
widget into it.

So, if you are looking to pack many buttons, you should look at the  
different boxes : Gtk::VBox, Gtk::HButtonBox, etc.  
Or maybe, the Gtk::Table or Gtk::Fixed containers.

Look the containers in the doc :
