There is an empty layout element you can use IupFill()
http://webserver2.tecgraf.puc-rio.br/iup/en/elem/iupfill.html
it does autoexpand to fill empty space around a widget.
if you are not decorating your labels with colors you could use something
like this instead of a simple IupLabel to center vertically a widget:
VBox
- Fill
- Label (without expand vertical)
- Fill
