XPages are a completely new way of developing web applications and as such do not sit inside your existing designs. You'll need to replace individual forms rather than just subforms.
That being said you can make use of your existing form design to save having to re-write all of your computed fields etc. by using the "ComputeWithForm" property of your data binding in the XPages.
As a getting started guide, I'd highly recommend Declan Lynch's series of articles: http://www.qtzar.com/blogs/qtzar.nsf/htdocs/LearningXPages.htm
