Call plugin for Skype for Business - user-interface

Question

I am trying to:
Use a program written in Visual C++ as a plugin in Skype for Business
or
Make the program window follow (attach itself to) the bottom of the Skype for Business user interface, using some type of tracker.
Any advice, or help on where to start?
I found the below links which would use Windows scripting tools such as AutoIt or AutoHotkey. I am not sure if this is the right approach.

https://www.autoitscript.com/forum/topic/120474-attaching-a-gui-to-another-window/
If it is the correct approach, then, where do I start? If it is not the correct approach, what else can I do?
This question might seem as a duplicate to this link. Yet, the question was discarded.

This AutoHotkey script allows you to attach a notepad window to an explorer window:
#Persistent
SetTimer, attach_window, 200
Return
attach_window:
IfWinNotExist ahk_class CabinetWClass ; explorer
return ; do nothing
IfWinNotExist ahk_class Notepad
return
; otherwise:
; retrieve the position and size of the explorer window:
WinGetPos, X, Y, Width, Height, ahk_class CabinetWClass
; attach the notepad window to the right side of the explorer window:
WinMove, ahk_class Notepad,, X+Width, Y
; To make the notepad window attach itself to the bottom of the explorer window use:
; WinMove, ahk_class Notepad,, X, Y+Height
Return
