Try this (untested, but it should work):

class MyWindow(wxPanel):
    def __init__(self, parent, ID):
        wxPanel.__init__(self, parent, -1)

        box = wxBoxSizer(wxVERTICAL)
        box.AddWindow(wxButton(self, -1, "one"), 0, wxEXPAND)
        box.AddWindow(wxButton(self, -1, "two"), 0, wxEXPAND)
        box.AddWindow(wxButton(self, -1, "three"), 0, wxEXPAND)
        box.AddWindow(wxButton(self, -1, "four"), 0, wxEXPAND)

Using -1 for the wxButton id argument lets wxPython make up a new id for
each button. When you use 1, it sets ALL the button ids to 1.
