Personally, I don't think you need to waste time on a Wizard.
These were developed, initially, for a mainstream OS which has users of varying levels of ability.
I think the GUI is the way to go. If a person has the skills required to be able to want to use an Installer app then it would be safe to assume they wouldn't need a wizard.
Develop your app.
Release it.
Build a userbase.
Develop the wizard (later) should your userbase require it.
Good luck. I think it's a worthy idea which should see the light of day. When it is complete - any chance of a port to AROS?
