I don't think opaque means what you think it means:
http://mw1.merriam-webster.com/dictionary/Opaque. The best option for
transparency is probably to look at the .NET framework in Windows, via
IronPython. I only say that because I know that I've seen demos of
transparent windows in .NET that were native to Windows and simple to
implement. I don't know if you can do transparency in wx, but I would
certainly check out the wxPython demos first to see if it has
anything. http://www.wxpython.org. wxpython would give you cross
platform support, if it works.
