Welcome to WebmasterWorld [webmasterworld.com]!
For a backgrounder and links to good tutorials, check out this Introduction to mod_rewrite [webmasterworld.com].
You don't actually want to ignore "/widget_item_" - you will need to match it (detect it) in order to extract the parameter (14 in your example) that you need to pass to your script. Similarly, you'll want to match the trailing ".htm" to make sure you're rewriting only the desired requests.
You will need to modify your script or page templates to output friendly URLs for users and search engine spiders. mod_rewrite [httpd.apache.org] will then convert them to the proper format to call you script.
Have a look at the Introduction cited above *and* at the links cited in that post -- You'll need to understand this material in order to get your code working. We are glad to help you get your code working, but please review our charter [webmasterworld.com].
