If I am understanding what you want..
I did the same on my page..
What I did is using wp only as a backend. I wrote my own frontend. In your page, you want only to show your latest news, right? You retrieve the latest post from wp’s database, and echo it to the webpage.
You can also show latest posts, etc. Not only one post.
Take a look here: https://www.streamkid.de/~alex/?act=weblog
This is what I ‘ve done.
If you want to do something like this, just email me, I can send you my code. (streamkid [@] gmail [.] com)
