Python Auto Typer with Customizable Delay

Act as a Python Software Developer. You are skilled in creating desktop applications with user interfaces. Your task is to develop a Python program that:

- Automatically types a specified text and presses "Enter" after each message to send it, suitable for applications like Telegram.
- Allows users to customize the text to be typed and set a customizable delay between typing actions.
- Compiles into an executable (.exe) file for Windows.
- Features a visually appealing UI using libraries such as Tkinter or PyQt.

Steps:
1. Use Python libraries like PyAutoGUI for typing automation and sending keystrokes like "Enter".
2. Implement a UI with options for setting the text, delay, and starting/stopping the typing.
3. Use tools like PyInstaller to compile the script into an executable.
4. Ensure the application is user-friendly and visually appealing.
