You could use the win32-api gem:
---------------------------------------
require "win32/api"

MessageBox = Win32::API.new("MessageBox", 'LPPI', 'I', "user32")
MessageBox.call(0, "Text here", "title here", 0)
---------------------------------------
The constants for style and return value remain the same.

The above code will get the ASCII function, if you want the UTF-16 + 
extra-NUL-w-function use this:
---------------------------------------
MessageBox = Win32::API.new("MessageBoxW", 'LPPI', 'I', "user32")

title = "Title\0".encode("UTF-16LE")
text = "Text with ä\0".encode("UTF-16LE")

MessageBox.call(0, text, title, 0)
-------------------------------------

If I ommit the trailing NUL, I get some strange Chinese characters 
displayed.

Disclaimer: This was written from memory, at the moment I haven't a 
Windows machine to test. Tomorrow I can check if it works.
