Funny.  I've been trying to get this to work all day, no go.  I browsed through
the 1.0 code, and there looks like there is little support for it.  The
1.1 code looks like it works, but only when XmNtraversal = True.

Here's the results of a " grep helpCallback *.c " in the 1.0 sources:

FileSB.c:                       XtCallCallbacks (fs, XmNhelpCallback, &temp);
Gadget.c:     XmNhelpCallback, XmCCallback, XmRCallback, sizeof(XtCallbackList),
Gadget.c:   XtRemoveAllCallbacks (gw, XmNhelpCallback);
List.c:    XtCallCallbacks(lw,XmNhelpCallback,&cb);
MainW.c:        XtCallCallbacks(mw,XmNhelpCallback,&cb);
Manager.c:     XmNhelpCallback, XmCCallback, XmRCallback, sizeof(XtCallbackList)
,
Manager.c:   XtRemoveAllCallbacks (w, XmNhelpCallback);
PanedW.c:      XtCallCallbacks (w, XmNhelpCallback, &call_value);
Primitive.c:     XmNhelpCallback, XmCCallback, XmRCallback, sizeof(caddr_t),
Primitive.c:   XtRemoveAllCallbacks (pw, XmNhelpCallback);
ScrolledW.c:        XtCallCallbacks(sw,XmNhelpCallback,&cb);
TextIn.c:    XtCallCallbacks(w, XmNhelpCallback, (Opaque) &cb);


You can see that the FileSB widget supports it, probably through its help
button, not translations.  The List widget appears to support it, as well
as MainWindow, PanedWindow, ScrolledWindow and Text.  In 1.1, the support
is centralized in the XmPrimitive class, but again, only if traversal is
on.
