基于wxpython实现的windows GUI程序实例

# using a wx.Frame, wx.MenuBar, wx.Menu, wx.Panel, wx.StaticText, wx.Button, 
# and a wx.BoxSizer to show a rudimentary wxPython Windows GUI application
# wxPython package from: http://prdownloads.sourceforge.net/wxpython/
# I downloaded: wxPython2.5-win32-ansi-2.5.3.1-py23.exe
# if you have not already done so install the Python compiler first
# I used Python-2.3.4.exe (the Windows installer package for Python23) 
# from http://www.python.org/2.3.4/
# tested with Python23   vegaseat   24jan2005
