Including html from a quickbook document

A very newbie question this.  I apologize in advance.

I need to publish some documentation for a C++ library. I'm using 
quickbook, with emphasis on the "quick": I'm hoping it will let me do 
all I need without having to learn the whole set of tools that it relies 
upon.  So far that has been working out okay.

Now the obstacle: I need to include some html (a paypal button) in one 
of the documentation pages.

Is there a way to include an html file using quickbook markup?  Or am I 
better off scripting something so it gets inserted during the build process?

Cheers,
