Using WordPress Menu on External Pages

Hi,

I am just setting up a website which will have wordpress as the landing page for news and blogging. Core features of the website will reside outside of wordpress and I want to get the look and feel of the WP portion similar to the non WP portion of the site, in particular the navigation bar.
I have created a main navigation bar in wordpress and I am trying to use that same, or identical looking nav bar in the header of my non wp pages of my site.
Is there an easy way to do this?
I tried to re-create the menu from the page source output and link to the WP css but could not get it to work.
Any input appreciated.
