I'm afraid that, no, there isn't a way to embed a Form Builder form onto a CMS page.

However, for your site I think there is a simpler and better solution. If what you want is a "contact us" form, then you can use the Email Contact Form includelet on any CMS page, and you don't need to use the Form Builder at all.

Here's an example of it in use: http://e-voice.org.uk/demosite/about-us/contact/

Just go to the Layout tab for your Contact Us page in the CMS, and add the includelet to the page.

I hope that helps!
