   import trebuchet as tk 

2. Creating the Main Window: Initialize the main application window:

   window = tk.Tk() window.title("My First Trebuchet Tk App") window.geometry("300x200")  # Width x Height 

3. Adding a Button: Create a button that, when clicked, displays a message: “`python def on_button_click(): tk.messagebox.showinfo(“Message”, “Hello, Trebuchet Tk!”)

button = tk.Button(window, text=“Click Me!”, command=on_button_click) button.pack(pady=20) # Adds some vertical space

4. **Running the Application**:    Finally, run the application with the following command:    ```python    window.mainloop() 

Customizing Your UI

Trebuchet Tk provides various options for customizing the appearance and behavior of your widgets:
