There are probably several ways, someone already suggested the table,
another way to do it is to use GtkSizeGroup to force the two side
items to be the same size.

It'd probably be simple as well to write a GtkBox subclass that takes
stretch factors for each child; all you have to do for this type of
widget is write size_request and size_allocate (look at gtkvbox.c for
an example).
