i played around with it a bit, and with the minor fix i just committed 
to cvs, this code:

$view1->signal_connect (button_release_event => sub {
        my ($textview, $event) = @_;
	my @coords = $textview->window_to_buffer_coords ('text', 
$event->coords);
        my $iter = $textview->get_iter_at_location (@coords);
        $iter->backward_word_starts (1);
        $iter_end = $iter->copy;
        $iter_end->forward_word_ends (1);
        print "clicked on '"
            . $textview->get_buffer->get_text ($iter, $iter_end, 1)
            . "'\n";
        0
});

prints out the word you clicked on.  quite cool.  note the important 
call to window_to_buffer_coords --- without that, it always thinks 
you're scrolled to the top.
