if you want to have more universal solution (e.g. split in half an inner panel) you can use grow parameter of a dedicated add method (but you won't be able to use dsl builder functions for VPanels):

hPanel {
                width = 100.perc
                add(VPanel {
                    // ...
                }, grow = 2)
                add(VPanel {
                    // ...
                }, grow = 2)
            }
