Basic element questions

For some reason, I'm just not getting how to use the menu system. How
does one organize menu elements? My inclination is to create a holder,
add controls to it, and add the holder to the Desktop, like adding
buttons to a div and positioning the div in a web page. Do
guiWindowHandle objects act as divs? I can add things to them, but I
can't position them on the Desktop (they always appear at 0,0).

I can add guiButtons to the Desktop and position them. I can also
position them within a guiWindowHandle object I place them in, just
can't position that window on the desktop.

In short, what's the hierarchy for the system? Do I add everyting to
the desktop, or is there some sort of tree of elements I should be
creating, and what class of elements belong at what level in the tree?
Also, how should I position elements? I currently use the Position
property and do the math for layout myself.

Aha. Using Desktop.AddChild instead of Desktop.Children.Add made the
difference. I'm guessing some layout logic isn't being performed with
Add.
