Hows this?  Child is a constant 200 pixels...
If the parent window is 300 pixels or less, it will stick to the bottom;
otherwise it will be a constant height as well...

At least I think this is what you were looking for...

child)

-- force an initial resize
VOID = invokeHandler( main, w32HResize, {0,0,0} )
WinMain( main, Normal )
