Help Please (Spell Check in Java)

I need a program that will read words from a text file and construct a binary tree search. After creating the binary tree, the program will prompt user to enter the name of the document to be checked.
Program will read the document reading each word and checking it with the words in the binary search tree. If the word is not found the program should give an option to
a. correct the spelling
b. ignore word
c. add to text file.

IF anyone can shed some light it would be very very much appreciated.

Cheer,
EF_GuY.
