	- Now, process events until widgets are displayed
	  **** How do I do this ****

You process events with a loop consisting of

	while (XtAppPending(...)) {
	    ...
	    XtAppNextEvent(...);
	    ...
	    XtDispatchEvent(...);
	    ...
	}

(this is precisely XtAppMainLoop, substituting XtAppPending
for True).  You might find it desirable to call XFlush before
the loop in some circumstances, or even XSync just before
XtAppPending to insure that the client and server queues are
completely emptied before continuing.

But have you considered using "work procedures"?
See XtAppAddWorkProc().
