All I can think to say is "don't do it"! If this dialog is to show an error or to gather more user input, then how would this work in an unattended install? What if the installer is invoking this custom action from an elevated state? If you need a custom UI, then I would highly suggest in investigating burn. With burn your MSI can remain pure and property driven.
If I had to guess, the reason you are having issues is because either you are invoking this custom action in a deferred state under the system context (in which case it doesn't have access to your desktop) or you are trying to create a MFC dialog from a dll. I seem to remember having to do some extra work to get a dialog to display from a DLL.

Is this possible as I've been trying to do it and am getting nowhere and now I'm thinking that I could be wasting my time if WIX does not support this.
