Class architecture / Pattern for Wizards

[Pondy Prem]

Dear David Kane:
Welcome !
I am desigining a wizard that has multiple execution-paths / branching-paths.I wish to know whether any design pattern exists for Wizard creation and control related issues.
and specifically about:
1. What are the collaborating classes to be used & relationship?
2. Who should create the wizard frame ?
3. Who should listen for "Back" "Next" "Cancel" Buttons ?
4. Who should decide what is the next/prev panel to show
5. Who should track the current state of the wizard-process ?
Looking fwd for your suggestions.
Thank you,
Prem

Command and State patterns immediately come to mind. Depending on your situation you may use a Bridge/Adapter etc also. Factory patterns are omni present in such situations.
Study the patterns and you shall find your answer.
