That looks good to me. Note that you can use this syntax instead of setXXX() 
if you prefer:

require 'Qt'
include Qt

 a = Application.new(ARGV)

image = Image.new("/home/navindra/out.png")
pixmap = Pixmap.new(image)

label = Label.new(nil)
label.pixmap = pixmap
label.show

a.mainWidget = label
a.exec
