That was not entirely correct, it turns out.  While
gtk_settings_get_default is not bound in perl-Gtk2 (patches welcome),
gtk_widget_get_settings is.  So try this:

perl -MGtk2=-init -E'my $w = Gtk2::Window->new; my $s =
$w->get_settings; say $s->get ("gtk-font-name"); $s->signal_connect
("notify::gtk-font-name", sub { say $s->get ("gtk-font-name"); });
Gtk2->main ();'

To parse the font name, you can use Pango::FontDescription->from_string.
