Python Rock-Paper-Scissors Desktop Game Development

I'm looking to enhance my text-based Python "Rock-Paper-Scissors" game with a graphical interface. The following features should be included:

- **Graphical Interface**: This feature should be designed for a desktop application.
- **Single-Player Mode Only**: There is no need for multi-player functionality at this time.

Ideal candidates for this project should have experience in:
- Python programming, particularly in game development.
- Developing desktop applications.
- Implementing graphical interfaces.

Please note that this project does not require multiplayer capabilities - it is a single-player desktop game.
