  First piece of advice: Use a resource construction program (RCP). Building
GEM resources by hand is a mind-numbing experience that's no fun for the
average human being.

  Now, if you were to have many G_TEXT objects (strings for your messages)
in your root box, they would be children of the root (since they are _inside_
the box). The G_BOXTEXT button would be another sibling to them. Basically,
your object tree would look something like:

				Root box (G_BOX)
			____________/   \_______________
                       |				|
                       v                                v
                First G_TEXT <--> Next G_TEXT <--:--> G_BOXTEXT
                  string            string               button

  The numeric order doesn't really make a difference.

						B-)

P.S. I'm not a guru with the inner mechanics of GEM dialogs; I prefer to stay
in the stratosphere of the RCP. However, I'm pretty sure of what I have up
there.
