I found this little calculator skeleton using wxPython on a ftp site while I was looking for wxGlade templates. It looks very similar to the gnome calculator. The only event is to close the application, but you could easily fill in the math behind the keys with your own event defs.

import wx

class GridSizer(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(300, 250))

        menubar = wx.MenuBar()
        file = wx.Menu()
        file.Append(1, '&Quit', 'Exit Calculator')
        menubar.Append(file, '&File')
        self.SetMenuBar(menubar)

        self.Bind(wx.EVT_MENU, self.OnClose, id=1)

        sizer = wx.BoxSizer(wx.VERTICAL)
        self.display = wx.TextCtrl(self, -1, '',  style=wx.TE_RIGHT)
        sizer.Add(self.display, 0, wx.EXPAND | wx.TOP | wx.BOTTOM, 4)
        gs = wx.GridSizer(4, 4, 3, 3)

        gs.AddMany( [(wx.Button(self, -1, 'Cls'), 0, wx.EXPAND),
            (wx.Button(self, -1, 'Bck'), 0, wx.EXPAND),
            (wx.StaticText(self, -1, ''), 0, wx.EXPAND),
            (wx.Button(self, -1, 'Close'), 0, wx.EXPAND),
            (wx.Button(self, -1, '7'), 0, wx.EXPAND),
            (wx.Button(self, -1, '8'), 0, wx.EXPAND),
            (wx.Button(self, -1, '9'), 0, wx.EXPAND),
            (wx.Button(self, -1, '/'), 0, wx.EXPAND),
            (wx.Button(self, -1, '4'), 0, wx.EXPAND),
            (wx.Button(self, -1, '5'), 0, wx.EXPAND),
            (wx.Button(self, -1, '6'), 0, wx.EXPAND),
            (wx.Button(self, -1, '*'), 0, wx.EXPAND),
            (wx.Button(self, -1, '1'), 0, wx.EXPAND),
            (wx.Button(self, -1, '2'), 0, wx.EXPAND),
            (wx.Button(self, -1, '3'), 0, wx.EXPAND),
            (wx.Button(self, -1, '-'), 0, wx.EXPAND),
            (wx.Button(self, -1, '0'), 0, wx.EXPAND),
            (wx.Button(self, -1, '.'), 0, wx.EXPAND),
            (wx.Button(self, -1, '='), 0, wx.EXPAND),
            (wx.Button(self, -1, '+'), 0, wx.EXPAND) ])

        sizer.Add(gs, 1, wx.EXPAND)
        self.SetSizer(sizer)
        self.Centre()
        self.Show(True)

    def OnClose(self, event):
        self.Close()

app = wx.App()
GridSizer(None, -1, 'GridSizer')
app.MainLoop()

I didn’t find a glade template for this one, but I’m starting to lean away from using a gui builder. It seems more trouble than it’s worth. Alternatives anyone? I really hate the way glade feels; a wysiwyg approach would work a whole lot better/faster.
