You are right.  I'll write an implementation and commit it once CVS is up 
again.

Not every layout can be realized with vbox and hbox (that's why we need
grids) but that's the theory; in practice, most layouts can be realized
with just those two building blocks, and in most other cases you can find
a workaround, or reorganize things slightly to fit in a box system.

In particular, your layout can be set up with hbox and vbox -

<gsmarkup>
  <objects>
    <window>
      <vbox>

        <!-- Upper part of the window -->
        <hbox>

          <!-- First column -->
          <vbox>
            <hbox>
              <label>Supplier:</label>
              <textField width="100"/>
            </hbox>
            <hbox>
              <label>Customer:</label>
              <textField width="100"/>
            </hbox>
          </vbox>

          <!-- Second column -->
          <vbox>
            <hbox>
              <label>Carrier:</label>
              <textField width="100"/>
            </hbox>
            <hbox>
              <label>Provider:</label>
              <textField width="100"/>
            </hbox>
          </vbox>

        </hbox>

        <!-- Lower part of the window -->
        <scrollView width="500" height="250" />
      </vbox>
    </window>
  </objects>
</gsmarkup


Of course, I've put a textField where you want to put a popup, and a
scrollView where you want to put your custom instance.

Replacing textfields with popups might give you alignment troubles; try
using halign="wexpand" in all the popups to fix this problem.

The grid is not yet available -- but hopefully it's unlikely you'll need
it. :-)

You are probably in more need of comboBoxes and of good documentation and
examples - I'll try to do some more of that. :-)

Thanks for your reports, and let me knwo if you still have problems with
the layout.
