EasyandFastGUI Consultation

I'm currently working on an Expert Advisor and I need to create a user interface for it. Unfortunately, I'm struggling with my knowledge of EasyandFastGUI. I need someone who can show me how to open a second window in my existing project by clicking a button. Additionally, I want the user to be able to resize the window by dragging it. I would like to integrate dynamic scrollbars in the window, both horizontally and vertically. I also want to display information using a text label, such as the current margin. Currently, I'm looking for someone who can program and explain these requirements to me.  I will provide the existing code upon request.  

1. Extension of the existing window:
• Enhance user experience by allowing the opening of a new window upon button click.
• Introduce user-friendly dropdown menus or text input fields in the new window for easy configuration.
2. Use of text labels or labels:
• Incorporate text labels or labels to display and update important information, such as the margin value.
3. Dynamic resizing of the windows:
• Improve flexibility by enabling users to resize both windows effortlessly through drag-and-drop functionality.
• Ensure a seamless experience with automatic appearance of vertical and horizontal scrollbars when needed.
4. Creation of comprehensive documentation:
• Provide clear and user-friendly documentation that explains the implemented changes and enhances understanding of the system.
