>I need help with designing and interface that will search keys.
Your ability to describe the problem in detail is staggering.

>use of avl trees ,b-trees
One or the other? Both? For what purpose? Is the B-tree an external searching structure and the AVL tree an internal searching structure? Have you written the code for these trees or do you just expect their intended use to magically become clear when you have them implemented.

>it should be linked to a database and allow searching.
Would this database be the B-tree?
