There is an undocumented hidden method in TaskBarIcon called ShowBalloon which is only implemented for Windows.

From the source:

def ShowBalloon(*args, **kwargs):
    """
    ShowBalloon(self, String title, String text, unsigned int msec=0, int flags=0) -> bool

    Show a balloon notification (the icon must have been already
    initialized using SetIcon).  Only implemented for Windows.

    title and text are limited to 63 and 255 characters respectively, msec
    is the timeout, in milliseconds, before the balloon disappears (will
    be clamped down to the allowed 10-30s range by Windows if it's outside
    it) and flags can include wxICON_ERROR/INFO/WARNING to show a
    corresponding icon

    Returns True if balloon was shown, False on error (incorrect parameters
    or function unsupported by OS)

    """
    return _windows_.TaskBarIcon_ShowBalloon(*args, **kwargs)

I tested it on Windows with wxPython 2.9.4.0 and it works well.
