I made this buttonbar on bottom of dialog

how can i do to create a lower button than the buttonbar?
If you look at the figure, if I press a button that is the same height as the buttonbar, how can I make it lower than the buttonbar?
that is, maybe I don't explain well
since I created the button with the color of the dialog when you press a button it is not clear where the height of the button ends
