Amazon API select item

Every Amazon item has a unique ASIN, and this tool will help me find the ASIN of any item on amazon. Currently i am opening a browser and navigating [login to view URL] directly and then cutting and pasting the ASIN into my system. I need a page created where i can type an item into a textbox and it will use amazon's api to show me a list of possible matches. Then the user will click one of the results and i will store the ASIN (unique identifyer). Code must be done in vb.net but i am open to both winform or web based solutions.
