Wizard or page?

What would you recommend?

We have a "webform" we need to build and we have been talking about using a wizard to ease the steps of this form for the user. But we also talked about editing in these steps and that's why we are thinking about showing these "steps" on a page instead and let the user scroll...

Let me show you what steps we have:

1. Select what kind of report you want to build
2. Build your report by selecting what "modules" you want to show in the report
3. Select the users you want to send this to
4. Choose how often you want this to be sent
5. Done

You have now created a report but you forgot to add John Doe as a receiver of the report so you want to edit the report and add him.

Would you do this with a wizard or just show it all divided by headers?

Let me know!
