This piece of css will show you that it is perfectly possibly to create a good looking navigation bar without any images or javascript and just a couple of lines of css.
All you need to do is create a html file that contains a unordered list in it with your navigation links in it as <li>. You will then need to simply attach the css file to your html.
I hope this will help you to realise that it isn't all about huge flash navigation and rollover images.
You can find my example here.
