For window titles, no.  For titles on the screen, use :align =>
"center".

  title "Sudoku Solver", :align => "center"

You want the background to be green, not a gradient?
Try: background(green)

In newer versions of Shoes, this is :curve => 5.  It curves the
edges of the background rectangle.

You'll want to group the buttons each in their own slot.  (A slot is
the generic name for a `stack` or `flow`.)

  Shoes.app(:title => "A Humble Sudoku Solver ", :height => 546,
      :width => 640, :resizable => false) do
    background green

    btn = "123456789"
    9.times do
      flow :width => 206, :margin => 4 do
        9.times do
          button btn, :width => 66, :height => 56
        end
      end
    end
  end

I don't know if this is helpful or just more confusing, but Martin
DeMello recently wrote a crossword builder.  Maybe since sudoku and
crosswords are relatives, it might have some ideas you could use?
