import wx
__version__ = '0.0'

class InputForm(wx.Frame):
     def __init__(self, parent=None, id=-1, title=__file__):
         # or, if you prefer: ..., id=wx.ID_ANY, ...
         wx.Frame.__init__(self, parent=parent, id=id,
                                 title='%s v%s' % (title, __version__))
         panel = wx.Panel(self)
         sizer = wx.BoxSizer(wx.HORIZONTAL)
         panel.SetSizer(sizer)
         sizer.Add(wx.Button(panel, label='OK'), 0, wx.ALL, 10)
         sizer.Add(wx.Button(panel, label='Cancel'), 0, wx.ALL, 10)

class MyApp(wx.App):
     def OnInit(self):
         frame = InputForm(title='Data Entry Form')
         self.SetTopWindow(frame)
         frame.Show()
         return True

if __name__ == '__main__':
     MyApp(redirect=False).MainLoop()
