No spinner in 1.3.1....
May be you can write a JTextField and accept only numeric chars.
Try the method below :

Document lvDoc = lvTextField.getDocument();
lvDoc.addDocumentListener(lvListener);

in lvListener, you need to override these functions
void   changedUpdate(DocumentEvent e)
Gives notification that an attribute or set of attributes changed.
void   insertUpdate(DocumentEvent e)
Gives notification that there was an insert into the document.
void   removeUpdate(DocumentEvent e)
Gives notification that a portion of the document has been removed.

whenever there is digit in the document, remove them
