Need help updating software for crypto wallet

Hello freelancers, I need help using CoinMarketCap JSON API Documentation and compiling a windows wallet. I need to use a public api method ([login to view URL]) to get the marketcap, usd price, btc price, and supply. Then I need you to fix the total amount in overview, with adding the total value in usd. I have an image attached that gives you clear visual instructions on what need to be added and where to add it. This is a simple project, it should take about a few hours to complete. Please don't ask for more money if I accept your bid. I need someone who has compiled a windows wallet before, knows json api doc, and c++. Thanks
