Use RadioButtons.

No, seriously.  ToggleButton, from which RadioButton inherits, has an  
object property named "draw_indicator".  In modern times this would  
be a style property, but it's apparently a holdover, and you can  
still use it in your code to make your RadioButton look like a  
ToggleButton, for whatever odd reason you may have (insert standard  
disclaimer about how only themes are supposed to be in charge of this  
sort of thing).


  #!/usr/bin/perl -w
  use strict;
  use Glib qw(FALSE);
  use Gtk2 -init;

  my $window = Gtk2::Window->new;
  $window->signal_connect (destroy => sub { Gtk2->main_quit });
  my $vbox = Gtk2::VBox->new;
  $window->add ($vbox);
  my $rb = undef;
  foreach (qw(one two three four)) {
      $rb = Gtk2::RadioButton->new ($rb, $_);
      $rb->set (draw_indicator => FALSE); # i'm evil
      $vbox->add ($rb);
      $rb->signal_connect (toggled => sub {
          print $_[0]->get_label." ".($_[0]->get_active ? "on" :  
"off")."\n";
      });
  }
  $window->show_all;
  Gtk2->main ;
