Wxpython is the python port of wxwidgets gui library. On ubuntu wxpython can be installed from synaptic. On windows it can be downloaded from the website wxpython.org
And here is a small program that pops up a simple window , to take a domain name and perform a whois for that domain.

Compile and Run
To run the program simply use the python command.
$ python whois_gui.py
It will launch a dialog box with an input text field. Fill in the domain name and press the "Whois" button. It will then fetch the whois details and display in the larger text box below.
Make sure that you have wxPython installed on your system. On Ubuntu you can install wxPython from the default repositories.
On Windows you have to download wxPython from the official site
https://www.wxpython.org/
