Facebook Page Booster GUI

Develop a graphical user interface (GUI) application in code that helps users boost their Facebook pages effectively. Ensure the application includes features such as scheduling posts, tracking engagement metrics, and suggesting optimal times for posting based on user data. The GUI should be user-friendly, visually appealing, and include instructional tooltips for each function. 

1. **Define the Application Requirements:**  
   - List the desired features like post scheduling, analytics tracking, and boost suggestions.  
   - Identify the target user demographic (e.g., small business owners, influencers).  

2. **Choose a Programming Language and Framework:**  
   - Decide whether to use Python with Tkinter, Java with JavaFX, or another suitable framework.  

3. **Design the GUI:**  
   - Create wireframes for the main window and additional dialogs.  
   - Plan navigation and layout for ease of use.  

4. **Implement the Functionality:**  
   - Write code for features such as scheduling posts and integrating with Facebook's API for engagement tracking.  
   - Ensure correct error handling and user feedback mechanisms.  

5. **Test the Application:**  
   - Perform usability testing and gather feedback to improve the application before release.

6. **Deploy and Maintain:**  
   - Package the application for distribution.  
   - Plan for future updates based on user feedback and Facebook API changes.  

# Output Format  
The output should be a detailed code sample demonstrating at least one of the main features and pseudocode for the overall application structure. Additionally, provide screenshots of the GUI design where applicable.

# Examples  
1. A sample Python function to schedule a post to a Facebook page.  
```python  
def schedule_post(post_content: str, post_time: str):  
    # Code to schedule a Facebook post  
    pass  
```  
2. Mock-up screenshot of the application layout, showing buttons for scheduling and accessing analytics.  

# Notes  
- Ensure that the application complies with Facebook's policies for third-party integrations.  
- Consider user experience and accessibility when designing the GUI.
