If your problem is reading the data from the file, you can use for example StreamReader for the purpose, see:

How do you present the data is a different issue. If the file contains only information about the choices made during the process, you could put a nice treeview to show different choices grouped in relevant groups, just like directories (for example based on the pages or forthcoming actions).
