I doubt there's a GUI which can help with what you want. As for programmatic way of doing this, please refer to the following thread where I already tried to answer a similar question: http://groups.google.com/group/tesseract-ocr/browse_thread/thread/6322a29f28ba49dc/f98699a9caf36dbc#f98699a9caf36dbc
If you see no clues in these posts then you need to send your sample images, there's no other way to help you.
