Is there a way to embed Worpress on your website? Currently, I have Blogger embedded in an I-frame but I would really like to switch to WP.

I want my site to look something like this: HERE (http://www.seductivesiren.com) (if you look at her froggy skin, that's the look I am going for)

So, can it be embedded in my site or do I have to kind of build my site around the WP blog? I would prefer not to have the suffix of ".PHP".

Thanks for any help you may be able to offer!
