Custom GUI Development for RDP Program

I need a custom GUI developed for my RDP program, which serves as the front end for my server.py application. The GUI should align with the 'sorillus' theme, a few of the specifics for this project are:

- **Functionalities:** The GUI should cater for a login interface. It should also facilitate a user-friendly interface for the RDP program.
- **Login Mechanism:** I envision a standard username and password login mechanism for security.
- **Theme Alignment:** It's important that the GUI be designed to match 'sorillus' in terms of color scheme and layout.

Ideal skills and experience for this project include:
- Proficiency in GUI development, especially in Python.
- Understanding of RDP programs and associated protocols.
- Experience with integrating login mechanisms.
- Ability to design UI elements to align with a specific theme.
- Prior experience working with 'sorillus' or similar design themes would be a plus.
