Thanks! this is really helpful it allows me to see how to do boarders 
and this is probably more of what i would use instead of input boxes but 
even though this is something that is very helpful i would also like to 
see how to do this with inputboxes. Like is there a way to have a number 
preset in the box and then when you press the button it adds one to it 
much like this just with an inputbox instead of a boarder.

This is something else i tried but of course it didnt work

require 'tk'

hello = TkRoot.new do
  title "Hello World"
  # the min size of window
  minsize(400,400)
end

number = 1

def addnumber
  @text.value = number
end

@text = TkVariable.new
lbl = TkEntry.new('textvariable' => @text) { justify 'center'
  pack('padx'=>5, 'pady'=>5, 'side' => 'top') }
TkButton.new() {
  text "Add One"
  command proc {addnumber}
  pack('side'=>'right', 'padx'=>10, 'pady'=>10)
}
Tk.mainloop
