Widgets are parts of programs.  Windows, on the other hand, are not.
If you spawn a different program, it has a new set of widgets (a copy).
The windows, on the other hand, are a different thing; both processes
have the *same* socket connection and thus (conflicting) control over the
same set of windows, until the socket is closed somehow (you don't want
to play with this).

What I would do is have process2 send process1 a signal, for which the signal
handler in process1 would unmanage/popdown the dialog. If you are not
using unix, you can still use property events, or ICCM (inter-client
communication).  Time to read up, if this is the case.
