looking for gui for python code

[Zentrader]

Whatever you use, it has to have a Python binding.  Spectcl may or may
not as you may be able to use it with the tkinter binding, but that is
doubtful.  Most GUI toolkits have an existing app to look for files in
a directory, if that is what you are wanting to do.  The following
link is to the GUI portion of the Python web site.
