Hello CodeTrasher,
Although the documentation for BBB GUI is incomplete, BBB GUI is essentially a wrapper library of the Win32/Windows API. Here are some general resources that could help you out.
Controls library: Here is a good place to start for learning about specific controls.
Windows and Messages: Here is the place to learn about windows controls and the message queue.
Control Spy: A useful sandbox for learning how various styles, notifications, and messages effect controls.
In regards to your situation, what you need is to add the 'WS_CHILD' style to the window you want to anchor. In addition to that, the window that is being anchored must not have WS_CAPTION, WS_OVERLAPPEDWINDOW, or WS_TILEDWINDOW styles (By default, all windows with title bars can be moved by the user).
Here is the documentation for all the window styles.
Here is a quick example for you.

If you want a child window with a title bar that can't be moved, I could elaborate how you could accomplish that if you are interested.
Good luck with your AI programming challenge. Feel free to ask me more questions if you need help.
