Yahoo Webhosting

I started a website on Yahoo Webhosing and signed up for a new wordpress blog to be on my website. I do NOT want it to be on the homepage of my website. Instead, I want a button that says ‘BLOG’ and I want people to click the button and wah-lah, they get my blog. However, I want the same theme and buttons on my blog page to be the same as the rest of my website. Any help out there???
