Thanks. I wanted something simple to start with, and after reading
Curses::UI::Buttonbox's doc page, I created a simple example that works:

#!/usr/bin/perl

use strict;
use warnings;
use Curses::UI;

my $cui = new Curses::UI (-color_support => 1);

my $my = $cui->dialog(
-message => 'Hello World.',
-buttons => ['yes', 'no'],
-values => [1, 0],
-title => 'First Dialog',
);

__END__

'Yes' and 'no' are pre-defined button names. Perhaps the example code in
Curses::UI should be changed.

I mean, perhaps the documentation in Curses::UI should
be changed.

Agreed. The best way for this to happen is to log a request
on rt.cpan.org.
