Here are several tutorials:

• Creating JSF Custom Components – Contains classic credit card example, JSF 1.0 targeted (old!)
• Building Custom JSF UI Components – Simple output component, JSF 1.1 targeted.
• Guidelines for designing JSF custom components – Sun/Oracle’s guidelines. JSF 1.x targeted.
• JSF Component Development – Extended label component, JSF 1.1 targeted.
• Creating a custom JSF 1.2 component – Shuffler component, JSF 1.2 targeted.
• Creating JSF div component – Simple div component, JSF 1.1 targeted.
• Custom JSF component – Birthday – Displays today’s date and birthdays, JSF 1.1 targeted.
• Component writing checklist – Overview of differences in JSF 1.0/1.1 and 1.2.

Take your pick. The first and the last ones seems very useful for your particular purpose. I however agree that a simple Validator is more than sufficient for this.
