using wordpress along with core php functionality

Hi!
i need a create a website which is in core php, but i need wordpress for two links i.e. News and blogs and rest all other pages should be outside the wordpress folder along with the home page(index page).

I had done previously this by keeping .htaccess and index outside my wordpress folder and using blog and some othe links. But that time i had my home page also in wordpress.

But i dont want home page to be inside the worpress folder.

Can any one help.

Thanks
uday
