Python Construction Cost Tracker to EXE

I have a Python script for a simple construction cost tracker that I need converted into a Windows-compatible executable with a simple graphical interface.

Key Requirements:
- Convert Python code to a running .exe
- Implement a simple graphical user interface (GUI)
- Ensure compatibility with Windows

Additional Information:
- Currently, no additional features are needed in the executable (like report generation, data export, or user authentication)
- The focus is solely on the conversion and GUI implementation

Ideal Skills:
- Proficiency in Python
- Experience with GUI development
- Knowledge of Windows executable creation

Please note, the project does not require any advanced features or interfaces, nor compatibility with other operating systems.
