Here is a simple, working example of this. It creates a custom log
handler that logs to a wx.TextCtrl and sets up the logging module to log
to the custom handler and also to the console.
This is pretty much my first wx program and I whipped it together *very*
quickly (mostly copy-and-paste from the "wxPython in Action" sample
code) so no points for style, but it does work. Every time you click the
button it will generate a log event.
