Grouping seems to be achieved by setting the window_group component of
the WM_HINTS property of the window:

https://www.x.org/releases/X11R7.6/doc/xorg-docs/specs/ICCCM/icccm.html#wm_hints_property

ICCCM goes on to say that "The window group leader may be a window that
exists only for that purpose <...> [not] mapped either by the client or
by the window manager".

Is that enough of a direction? I have only ever written X11 code using
xcb, not Xlib, but I could try to help further if needed.
