How to create a random word generator program

One use of a word generator application is to generate new website domain names
A word generator works like this:

1. You store all the consonants in box A
2. You store all the vowels in box B
3. You let computer randomly pick some consonants from box A into a new box called box C
4. The computer also randomly picks some vowels from box B into box C
5. Now box C contains both consonants and vowels.
6. Finally, you let the computer randomly arrange the content of box C. Whatever is the result of this arrangement is the 'generated word'
