It has nothing to do with Outlook. It depends on your development platform.

For VBA you'd use a VBA UserForm, for .NET code you'd use a Windows Form,
for unmanaged code you'd use a form provided by your development
environment.

You'd show the form when you want, set a timer control to fire after an
interval you select, and when the timer fires you close your form.
