Not at all.

Set XtNtop and XtNbottom to ChainTop and XtNleft and XtNright to ChainLeft.

[ Here is some more info that may be of help.
  From my postion to xpert on Dec. 16 1988 ]

The form widget is a slippery character and is difficult to describe and
understand, we are looking into getting something better, but for a while
for doing general widget layout the form is it.  So to let people use it more
effectively I will try to give a better explanation of its use.

The form has two distinct methods of laying itself out.  Method 1 never
resizes the children of the form, and just attempts to place them in next
to each other like building blocks, according to the resources shown below.
The FromVert resource is used to place this widget directly below one of its
siblings.  The fromHoriz resource is used to place this widget directly to the
right of one of its siblings.  This method is used when managing and unmanaging
children, and processing childrens geometry requests.

Method 2 may resize children if the XtNresizable constraint resouce is set
for that child.  This method takes each edge of each child, and moves it 
appropriately, for instance in the above example you may want to 
chain both the top and bottom edges of the lable widget to the top of the
form.  This will of course keep it from changing size, and both edges are
fixed to the top of the form.  For really strange behavior you can chain the
top of a widget to the bottom of the form, and the bottom of a widget to the 
top of the form.  This method is only used when the form is told to resize
itself by its parent.

Resources for each method of laying out the form widgets children.

Method 1				Method 2
--------------------------------------------------------------
XtNfromVert				XtNbottom
XtNfromHoriz				XtNtop
XtNhorizDistance			XtNleft
XtNvertDistance				XtNright
					XtNresizeable

Back to the specific question:

The only what to get the label widget to go all the way across the form 
like you are asking is to size it appropriately.  This can be done by querying
the daughter form widgets of their sizes (a call to XtFormDoLayout may be
necessary) and the label widget of its XtNhorizDistance resource, and adding
them all together as the correct size of the label widget.
