The GUI tool is an interface written in PyQt5. It utilizes an instance of the CLI wrapper class to communicate with the CyDAQ. The main code can be found under `gui/app.py` (start at the bottom of the file). The class MainWindow is the app's starting point; all other widgets/elements are added. It also contains a thread pool for running commands asynchronously and the CLI Wrapper. Each widget is also its class, which can all be found in the `gui/widgets/` directory.
