The Tcl/Tk manual is easy to find with google, for example:
http://www.tcl.tk/man/tcl8.4/TkCmd/contents.htm

0. Ensure this works:
    require 'tk'

1. To convert the Tk widget commands to Ruby class names, prepend "Tk"
and capitalise,
    for example the Tcl/Tk "entry" command becomes the Ruby class
"TkEntry"

2. To apply an option, just use the tk option name without the leading
'-',
     for example "-relief" is just "relief".

3. Options can be set in two different ways, either:
 a.  provide a hash of option value pairs, the option name is a string:
      example { 'relief' => 'ridge', 'width'=>3 }
      and hand this hash over as a parameter (you don't necessarily
need { } in a method call), or
 b.  provide a block, e.g. to new
      entry = TkEntry.new(root) do
            justify 'center'
            width 3
            borderwidth 3
            relief 'ridge'
       end
       # notice the option names are not quoted here, but look like
method names


The other thing you might want to do is take a look at this Ruby/Tk
tutorial

I haven't read this, but it looked interesting:
