Integrate WP into exsiting website template

I want to integrate my WP blog into my existing website template. I want to use my website template structure (my header/top nav bar/side nav bar/footer). I basically want to get rid of all of the fluff and only use the blog entry part of wp. I also want the transition from my website to my blog to be completely seamless. Is this possible? I am willing to change templates, but right now I think I’m using WP default Kubrick Template. I’ve tried the integration myself, but I really don’t know what to delete and where to add my content. any help would be so appreciated.
