Why are you using the logging module? All you need to do is redirect
stdout. See below:

Give this a try:

<code>

class XPinst(wx.App):
    def __init__(self, redirect=False, filename=None):
        wx.App.__init__(self, redirect, filename)

    def OnInit(self):
        self.frame = wx.Frame(None, -1, title='Redirect Test',
                              size=(620,450),
                              style=wx.STAY_ON_TOP|
                                    wx.DEFAULT_FRAME_STYLE)

        panel = wx.Panel(self.frame, -1)

        self.log = wx.TextCtrl(panel, -1, size=(500,400),
                              style = wx.TE_MULTILINE|wx.TE_READONLY|
                                      wx.HSCROLL)
        redir=RedirectText(self.log)
        sys.stdout=redir
        print 'test'

        self.frame.Show()
        return True

class RedirectText:
    def __init__(self,aWxTextCtrl):
                self.out=aWxTextCtrl

    def write(self,string):
                 self.out.WriteText(string)

</code>

If you use wx.App, you can also just set the "redirect" parameter to
True as well.
