See the Athena (Xaw) Dialog widget.

A text widget (asciiDiskWidgetClass in Xaw) See xmore or xless (in
contrib in R3/R4 respectively) for examples.

XtSetValues to set XtNgeometry for the toplevel shell before you
realize it.  Or set it via the app-defaults file.  (Is there a better
way?)

The Xaw manual, the HP widgets (Xw) manual, Doug Young's book "X
Window Systems Programming and Applications with Xt", and the Nutshell
book on Xt (Volumes 3 and 4)

In R4, mit/examples/Xaw has plenty of examples for the Xaw widgets.
The Xw widgets come with tests/ that make useful starting points.
Doug Young's book examples are available by ftp from
expo.lcs.mit.edu:contrib/young.examples.tar.Z or
cs.toronto.edu:pub/X/young.examples.tar.Z.  (The examples for the Motif
version of Doug Young's book are in
expo.lcs.mit.edu:young.motif.tar.Z) The Nutshell examples are in
uunet.uu.net:nutshell/xt/.
expo.lcs.mit.edu:asente-swick.examples.tar.Z contain more examples.
