IG.com Forex Trading API - demo for Java integration needed

I am looking for a Russian speaking programmer to develop a demo in Java which uses the API of Forex trading platform [login to view URL] to buy and sell forex. Working demo and full source code required. The demo should have a simple user interface where the user can set the necessary parameters to open a position such as which currency pair to trade, capital to invest, leverage ratio etc. There should be a button to buy and a button to sell the position. This demo integration will later be combined with an existing Java program. The demo should also show the current price of the USD/EUR currency pair from [login to view URL], current margin and a candle stick chart (to be updated continuously). I am just looking for a demo code which allows the user to buy and sell one position. If you can modify it so that it can open/close up to 10 positions that would be great. no intelligent trading algorithm etc is needed, everything is manual at this stage. The code should be fast. I will prefer Russian speaking programmers.
