they would have to be generated from a header, and thus most 
conveniently available in a separate module, loaded only if you want 
them -- like the Keysyms and Pango constants.

  sub make_dialog {
      use Gtk2::Stock;
      my $dialog = Gtk2::Dialog->new ("something cool", undef,
                                      'destroy-with-parent',
                                      GTK_STOCK_APPLY => 'apply',
                                      GTK_STOCK_CLOSE => 'close');
      ...
  }

the advantage of constants would be compile-time checking that you 
spelled the stock id correctly; when using a string, you don't find out 
until runtime, when the button says "gtk-spply" instead of having the 
apply icon, etc.
