There's an example of checking for numbers in the Code Barn: http://faq.javaranch.com/java/NumericTextField

Checking for a valid date would be similar, but would involve a more complex regular expression.

Any particular reason why you must use a JTextField as a date editor component? This is akin to living in the stone age (Just kidding).

You might want to consider the JSpinner which accepts a SpinnerDateModel.
JSpinner tutorials can be found here
Also you might want to take a look at this cool component.
