Hmm...
I don't know why you need such realtime reflection. 
I think you may have better solution for your problem.
However, if you really need it, for example, 
-----------------------------------------------------------
requrie 'tk'

v = TkVariable.new

TkLabel.new(:textvariable=>v, :relief=>:ridge).pack
TkButton.new(:text=>'add str', :command=>proc{v.value += 'str'}).pack
t = TkText.new.pack

v.trace('w', proc{t.value = v.value})
t.bind('KeyPress', proc{v.value = t.value})

Tk.mainloop
-----------------------------------------------------------
