How do I use this in a widget?
For text widgets add the following code to your template’s functions.php
add_filter("widget_text", "do_shortcode");See this site for detailed instructions:

You could also download the Sidebar Shortcodes plugin:

Thanks! Now how can I get the clicked links from the shortcode to be target=_blank?
Nancy, all of the links generated by the plugin has the rel=”external” attribute. All you need to do is use a bit of javascript to craft it to open in a new window. (target=_blank isn’t xhtml compliant).
See this thread on how to implement it.

Is it possible for the free blogs to support this kind of widget? Or can that not be done?
It depends of your blog provider allows plugins or not. You can also download the Wordpress blogging system and host it on your own server.
