text: Title: Windows GUI for matchering (Claude created)
  Body: PySimpleGUI-based GUI for Matchering
  
  I've created a simple GUI for Matchering using PySimpleGUI. This solution provides an easy-to-use interface for those who prefer a graphical approach over command-line usage.
  
  Features:
  - Select target and reference tracks via file browser
  - Choose output formats (16-bit WAV, 24-bit WAV, or both)
  - Simple 'Process' button to start Matchering
  - Error handling and completion notifications
  
  Requirements:
  - Python 3.x
  - PySimpleGUI
  - Matchering
  
  A. Install matchering as per instructions 
  
  python -m pip install -U matchering
  
  B. Install GUI
  pip install PySimpleGUI matchering
  
  C. Save the code below in a file called  
  matchering_gui.py
  
  in your matchering folder.

  Usage:
  1. Double click the file to run the script: `python matchering_gui.py`
  2. Use the GUI to select files and process audio
  3. Enjoy!
  
  This GUI provides a user-friendly alternative to command-line usage and might be helpful for users who prefer graphical interfaces. It's ugly as sin, but does the job.
  
  I take no responsibility at all, it's all Claude Sonnet 3.5's fault. :)
