1. Put a button on your existing website and have it link to your wordpress.COM blog http://support.wordpress.com/domain-mapping/map-subdomain/ You can map a subdomain of your existing website to your WordPress.com blog for $10/yr
2. Build a wordpress.ORG blog in a subdirectory of your existing website. Have your webmaster/host add WP in a subdirectory to your current website, and add navigation to the blog.
