What you need to do is set the minimum size attribute of the control.
For example, if you add the following line to widget-tester.lisp immediately
after the make-instance call for lb1 in the populate-list-box-test-panel
function

    (setf (gfw:minimum-size lb1) (gfs:make-size :width 200 :height 150))

this results in the left-hand list box being at least 200 pixels wide. And
because of the way this test program is coded, the right-hand list box is
also made to be the same width.

Now, you'll notice that the list boxes are the same height as they were
before this change. That's because the other components of the panels
in the window are such that 150 pixels is less than the available vertical
space, so the list boxes end up taller than that.
