Have a look at http://www.jython.org/docs/properties.html:
you can pass an ActionListener object, or a function with one argument.

You might try one of these: (untested)

self.catCombo = javax.swing.JComboBox(self)
# This assumes that actionPerformed method is available
# and that the current class implements ActionListener.

or

self.catCombo = javax.swing.JComboBox(actionPerformed = (lamda event, self=self:
                                                          self.actionPerformed(event))
# No need to inherit from ActionListener here.

I prefer to use the last form since it allows to choose a method from the current
class to be used as action listener.
You might call eg. self.exit(event) from the lambda.
