I already automate parts of WhatsApp Web with Python + Selenium, but I now need it wrapped into a clean Windows-only desktop application. Your task is to take my existing logic, extend a few predefined features I will share (think scheduled message blasts, dynamic contact selection, and media attachments), and present every parameter in an intuitive GUI. The stack must stay in Python and Selenium; for the interface you may choose Tkinter, PyQt, or Kivy—whichever lets you deliver a responsive, installer-ready EXE with no command-line setup for the user. Core expectations • Integrate my current scripts and add the extra functions I outline. • Build a stable GUI that lets users log in to WhatsApp Web, adjust each feature, and monitor progress in real time. • Package everything so it runs on Windows 10/11 with a single installer. • Provide clear instructions and well-commented code so I can tweak it later. If you have previous desktop automation or WhatsApp bot examples, share a short clip or repo link when you bid; it will help me decide quickly.
