How to show different widgets on different pages in a user friendly way

You can create your own sidebar if you want.

add the following to your functions.php

 register_sidebar(array('name'=>'Sidebar ',
    'before_widget' => '<div class="widget">',
    'after_widget' => '</div>',
    'before_title' => '<p>',
    'after_title' => '</p>',
));

and you can use this widget by using the following code

<?php dynamic_sidebar('sidebar')?>

Hope this helps
