Creating and configuring a cluster unaware app with user interface

Hi,

I'm trying to add an application with user interface into a cluster by following the step in the following link:

I can manage to finish the wizards and the generic application seems to work since by taking it offline and putting it back online, I can see the process disapear and show up again in the task manager. The only problem is: no GUI showing at all.

Did I miss anything here? If I did, what is the stardard way to put an application with user interface into a cluster? Even in the example of the above link, there is no notepad window pops up for users to type in. Thank you very much.
