This procedure will still allow the text to be selected, but won't allow 
for modifications, or even an insertion cursor.

  require 'tk'
  root = TkRoot.new()
  text = TkText.new(root){height 10; width 20}.pack
  text.insert('0.1', 'This is my message')
  text.state('disabled')
  root.mainloop

Height and width I did not set to 50 and 100, since those attributes for a 
TkText widget are in characters rather than pixels (and at least on my 
screen that results in a screen-filling widget).

The state attribute/method and the height/width idiosyncrasies are 
documented in the Tk documentation for the text command at 
http://www.tcl.tk. That's always the first place I look for stuff like 
this.

I'll have to look into TkMessage before I can comment on that... it's not a 
widget I've ever used.
