Yup. Here's some code from a PlayPause button that I have.

    my ( $widget, $programSettings ) = @_;
    if ( $widget->get_active ) {
        ...
        $widget->set_label('pause');
        $widget->set_use_stock(TRUE);
        $programSettings->{'MainTooltips'}->set_tip( $widget, 'Pause' );
        ...
    }
    else {
        $widget->set_label('play');
        $widget->set_use_stock(TRUE);
        $programSettings->{'MainTooltips'}->set_tip( $widget, 'Play' );
        ...
    }

    # update the button
    $widget->show;

$programSettings is a hashref that gets passed around everywhere. It's
used in the example to set tooltips. Both play and pause have been set up
as custom icons with an IconFactory; you can just as easily use
standard gtk stock icons there.

Basically, when the button is active, the program is playing, and the
button then represents pause mode. (And a lot of code's been omitted from
that section, obviously :) And then vice versa.
