Hi. I'm a programmer from Russia with strong skills in Python. You can see the full list of my skills on my profile page. I can make GUI for you using PyQt. Qt is a library (or framework) that provides convenient tools for creating graphical interfaces in particularly. If needed, I can use other libraries. As for additional features, could you describe them in details? Thanks.
If you're interested, feel free to contact me.
All the best,
Sergey.
