As long as you have the instance around, you should be able to access 
its attributes and methods.

ouch! no.

Here is a simple one that should make it clear:

class MyCheckDialog(wx.Dialog):
     def __init__(self, Choices):
         wx.Dialog.__init__(self, None, -1, 'wxDialog')
         self.Choices = Choices

         self.clb = wx.CheckListBox(self, -1, wx.DefaultPosition, 
wx.DefaultSize, self.Choices)

         ok = wx.Button(self, wx.ID_OK, 'Ok')

         sizer = wx.BoxSizer(wx.VERTICAL)
         sizer.Add(self.clb, 1, wx.EXPAND|wx.ALL, 5)
         sizer.Add(ok, 0, wx.ALIGN_RIGHT|wx.ALL^wx.TOP, 5)
         self.SetSizer(sizer)
         #self.Fit()

         self.Center() # make it come up on the center of the screen

     def GetChecked(self):
         Checked = []
         for (index, item) in enumerate(self.Choices):
             if self.clb.IsChecked(index):
                 Checked.append(item)
         return Checked


## And to use it:

a = wx.App()

myd = MyCheckDialog(['check', 'list', 'box', 'another'])
if myd.ShowModal() != wx.ID_OK:
     exit(1)
else:
     print "You checked:", myd.GetChecked()


If you put all that in a file and run it, you'll see how it works
