you have to call the create method on all widgets that have been 
instanciated later than your call to application.create.

also you have to call the reaclc method on the containing widget, in 
order to tell it, that it should make its layout new.

here is your working code:

#!/usr/bin/env ruby

require 'fox'

include Fox

class Test < FXMainWindow
   def initialize(app)
     super(app, "Test", nil, nil, DECOR_ALL, 0, 0, 640, 480, 0, 0)


    body = 
FXVerticalFrame.new(self,LAYOUT_SIDE_TOP|FRAME_RAISED|LAYOUT_FILL_X|LAYOUT_FILL_Y|PACK_UNIFORM_WIDTH 
)


 
topbuttons=FXHorizontalFrame.new(body,LAYOUT_SIDE_TOP|FRAME_RAISED|LAYOUT_FILL_X|PACK_UNIFORM_WIDTH, 
0, 0, 0, 0,20, 20, 20, 20)



     FXButton.new(topbuttons, "Add").connect(SEL_COMMAND) {add(body) }

     FXButton.new(topbuttons, "&Quit", nil, app, FXApp::ID_QUIT)

     end

   def add(body)

     lbl=FXLabel.new(body,"text 1")

     tf=FXTextField.new(body,numcolumns=20)

     lbl.create
     tf.create
     body.recalc
   end



   def create
     super
     show(PLACEMENT_SCREEN)
   end
end


application = FXApp.new("Test", "FoxTest")
Test.new(application)
application.create
application.run
