Are you sure you want to use a notebook paradigm? This strikes me has
having some pretty severe usability issues. For example, does the user
have to click on the next tab when it becomes available, or is it
switched to that automatically when the time comes? Either way this is
confusing to the user and does not represent the way a user normally
interacts with a dialog box that contains tabs.
What you are describing is more of a wizard-like interface with discreet
steps. The only thing is that you state you want the user to know
what's coming. This appears to me to be better done with a wizard-like
dialog box with a "Next" button, and maybe a frame on the left side of
the dialog box that lists all the steps and places a pointer on the
current step. This is typically how most UI's accomplish this.
