Hi rifie - welcome to Wolf!

Yep. Stick this in your Layout's sidebar area:
<ul id="nav_sub">
<?php foreach ($this->find('products')->children() as $child): ?>
<li><?php echo $child->link($child->title, (url_start_with($child->url) ? ' class="current"': null)); ?></li>
<?php endforeach; ?>
</ul>
That should do it for you. You might want to change the "id" of the UL list to something of your own choosing.
This is the "Simple in Sidebar" recipe from the Navigational Cookbook in the wiki, by the way. (Just inserting the "find" in line 2 so that it always points to your product listing.) It's a very useful part of Wolf's documentation.
Hope that helps! And do show us your site when it's ready.
