Posting Plug-in

I have just recently gotten wordpress installed on my host, and I have been loving it. One reason I got the blog was for my girlfriend to contribute to it while she is studying abroad next semester. However, she is not really good with navigating the admin panel. I have a feeling the look of it will scare her. Does anyone know of a plugin that will enable posting directly to the frontpage? Where all she will have to do is go to our site, login (or not) and start typing directly in a text box on the main page?

Any help would be appreciated…
