The following should work using a recent svn revision from kdebindings. 
However, it doesn't because findChild fails. I think it's a bug and I'll try 
to contact the developers to 

require 'Qt4'
require 'qtuitools'

class Dlg < Qt::Dialog
  
  slots 'test()'
  
  def initialize parent = nil
    super
    file = Qt::File.new File.expand_path('~/temp/test_ui.ui')
    file.open(Qt::File::ReadOnly)
    loader = Qt::UiLoader.new
    @widget = loader.load file, self
    file.close
    self.layout = Qt::VBoxLayout.new self
    layout.add_widget @widget
    @close_btn = @widget.findChild(Qt::PushButton, 'close_btn')
    @test_btn = @widget.findChild(Qt::PushButton, 'test_btn')
    connect @close_btn, SIGNAL('clicked()'), Qt::Application.instance, 
SLOT('close()')
    connect @test_btn, SIGNAL('clicked()'), self, SLOT('test()')
  end
  
  def test
    puts "testing"
  end
  
end

app = Qt::Application.new ARGV
dlg = Dlg.new
dlg.exec
app.exec
