Client/Server simpl JAVA App/class

I would lik a Java server class done with a client, the design and requirements are basic and simple. The server will push certain details to the designated client and recieve info back from the client. The client will receive the information, display it and collect user input. ## Deliverables Server : Class that will be instainitiated from my application.? It will allow sending of : 1. Order Number 2. Product Name 3. Product ID 4. Value (Optional) 5. Quantity Receive Back : 1. Client ID 2. Order Number 3. Product ID 4. Updated Quantity Client will allow two modes of view/operation: View/mode 1: Array of? very large? buttones in two lines Each button receives and updates the Quantity, product Name if a user pushes the button 1 is deducted from the quantity and the udpated value is sent back to the server. View/Mode 2: Array of very large buttons in two lines Each button receives and updates quantities and products grouped by orders (order number) if a user pushes the button, the whole order is subtracted. update value is sent back to the server The two modes should be configurable through INI/xml files. The two modes should be switchable within the application screen on the fly. The Screen size/resolution should be configurable (1024x800/ 800x600..etc)
