To clarify: something like this...
label1 := 'aaaa'.
label2 := 'bbbb'.
label3 := 'cccc'.
label4 := 'dddd'.
block1 := [....].
block2 := [....].
block3 := [....].
block4 := [....].
code which creates a RectangleLikeMorph (or the subclass PasteUpMorph
or another one like a window?) which in turns has 4 buttons with the
labels and blocks attached ---> a launcher.
