I'm not sure about what you mean by that, but have a look at this 
minimal example (tested with Ruby 1.9):
----------------------------------------
#!/usr/bin/env ruby
#Encoding: UTF-8
require "wx"

class MyFrame < Wx::Frame
  include Wx

  def initialize(parent = nil)
    super(parent, :size => Size.new(400, 400), :title => "Test")

    #Just to fill that empty window
    StaticText.new(self, :label => "This is a test GUI.")
    Button.new(self, :label => "This is a test button.", :pos => 
Point.new(20, 20))

    #1. Create the MenuBar.
    menu_bar = MenuBar.new

    #2. Create a menu you want to append to the menu bar.
    menu = Menu.new
    #3. Create menu entries. You could place submenus here to.
    menu.append(ID_PREFERENCES, "Preferences...")
    #This is a horizontal line.
    menu.append_separator
    #Yet another item
    menu.append(ID_EXIT, "Quit")

    #4. Now append the menu to the menu bar. The ampersand
    #sign & indicates that this menu will be accessible via
    #[ALT] + [F], i.e. [ALT] + [<next letter>].
    menu_bar.append(menu, "&File")

    #5. Set the frame's menu bar to our newly created one.
    self.menu_bar = menu_bar

    #Process the menu bar's events.
    evt_menu(ID_PREFERENCES) do |event|
      md = MessageDialog.new(self, :caption => "Testpreferences", 
:message => "Your preferences dialog goes here.", :style => OK | 
ICON_INFORMATION)
      md.show_modal
    end

    evt_menu(ID_EXIT){|event| self.close}
  end

end

Wx::App.run do
  mainwindow = MyFrame.new
  mainwindow.show
end
----------------------------------------

You may also have a look at bigdemo in the wxRuby samples directory 
(look where you install your gems to) and at the wxRuby forum at 
http://www.ruby-forum.com/forum/36.
