WPF multi-page free-form input

Question

In a WPF/Visual Studio 2010/C# environment interacting with an MS Access database, I need to design a multi-page form for "free-form" input(similar to typing within an MS Word document).  I would like to design this with two page templates:

(1) one with a "NEXT" icon/arrow at the lower right corner for all pages except the final page,

(2) one with a "STOP sign" icon at the lower right corner, signifying that no more pages follow.

Obviously, when input has begun, the current page will be the "final" page until input has reached the bottom of the page...then all of the input on that page will be shifted to a new "non-final" page with the succeeding page then becoming (maybe temporarily) the final page.

Any ideas as to how to design such an addition to my project?
