Yes, it is ;-)

The best way to do this is to hint the WM that the windows belong
together, eg. by setting the same leader (which can but does not have
to be one of the windows) or setting one as transient for the other
(what has other effects depending on the window type of the transient
one)

For the beginning, try KWindowSystem::setMainWindow() what will create
the transient connection and is - given your description - likely what
you want (eg. a QDockWidget is transient for it's main window)
You'd likely call that in the contact list and need to know
Widget::winId() from the message window.

To fake a group connection, you'll unfortunately but likely (i'm not
really sure...) have to set the releavant property using X11 directly
(XChangeProperty), so rather first try whether the above suits you well.

Yes. This is often caused by acting on mouse press instead of release,
but the timestamp check is faaaar more wonky than an explicit
connection, so the latter one is preferable.
