Having been made aware of the Python EasyGui project while reviewing "Hello World", I thought that maybe there should be an equivalent version for IronPython. So here is one (with just a minimal amount of fudging in places):
"""
@version: 0.3.93(2010-Mar-28)
@note:
EasyGui provides an easy-to-use interface for simple GUI interaction
with a user. It does not require the programmer to know anything about
tkinter, frames, widgets, callbacks or lambda. All GUI interactions are
invoked by simple function calls that return results.
EasyWPF is an API-compatible implementation for IronPython written against
the Windows Presentation Foundation
Note that EasyWPF requires .net release 3.0 or greater.

A dialog to get a file name.
About the "default" argument
============================
The "default" argument specifies a filepath that (normally)
contains one or more wildcards.
fileopenbox will display only files that match the default filepath.
If omitted, defaults to "*" (all files in the current directory).
WINDOWS EXAMPLE::
...default="c:/myjunk/*.py"
will open in directory c:\myjunk\ and show all Python files.
WINDOWS EXAMPLE::
...default="c:/myjunk/test*.py"
will open in directory c:\myjunk\ and show all Python files
whose names begin with "test".
Note that on Windows, fileopenbox automatically changes the path
separator to the Windows path separator (backslash).
About the "filetypes" argument
==============================
If specified, it should contain a list of items,
where each item is either::
- a string containing a filemask # e.g. "*.txt"
- a list of strings, where all of the strings except the last one
are filemasks (each beginning with "*.",
such as "*.txt" for text files, "*.py" for Python files, etc.).
and the last string contains a filetype description
EXAMPLE::
filetypes = ["*.css", ["*.htm", "*.html", "HTML files"] ]
NOTE THAT
=========
If the filetypes list does not contain ("All files","*"),
it will be added.
If the filetypes list does not contain a filemask that includes
the extension of the "default" argument, it will be added.
For example, if default="*abc.py"
and no filetypes argument was specified, then
"*.py" will automatically be added to the filetypes argument.
