I've been playing around a little with the wx.lib.masked.numctrl 
package. There's a control named NumCtrl that basically does what you're 
looking for. I reckon you might want to tinker around with it a little 
and see if it works for you. You might have to write your code in a way 
that it creates and binds the control to your pythoncard frame at init 
(override the __init__ method of the PythonCard.model.Background or 
PythonCard.model.PageBackground to load up the control)

eg.
from PythonCard import model,
from wx.lib.masked import numctrl

class myframe(model.Background):
    def __init__(self, aParent, aBgRsrc):
        model.Background.__init__(self, aParent, aBgRsrc)
        self._initControls()

    def _initControls(self):
        self.txtText = numctrl.NumCtrl(self.panel, value=1234)
        self.txtText.SetParameters(groupDigits=False, allowNegative=False,
            useFixedWidthFont=False, max=5, limited=True)
