If you read on the page in the link you gave . you will see this :
Placing WordPress Popular Posts in your templates
If you want to use WordPress Popular Posts somewhere else in your templates, simply place <?php get_mostpopular(); ?> where you want your listing to be displayed. Easy, huh?.
USAGE:
<?php if (function_exists(‘get_mostpopular’)) get_mostpopular(); ?>

Generally speaking, does this work with all widget-based plugins? Or does it vary?
depends on the plugin.
Most of them do add some function to the functions.php file, and in that case ,it will work. (changing the function name obviously)
