This is not a question, it's an advertisement for cluelessness. You talk about 'bookbuyeragent' code as if we should know what that is. You dump a ton of code on us. You tell us you have a GUI problem, but not what your problem is. Surely you realise that we can't possibly help you based on this post ?

hi .. thanx for reply ...
when execute this code there is nothing appear in GUI interface ...
OK, so you have edited your question, what a pity you did not take note of Christian's comments and explain where your code is failing and what you think is going wrong. I would suggest you spend some time with your debugger working out exactly where it is going wrong and then come back here with a more specific question.
