Desktop App That will Submit Data to a URL

Need Desktop app that will submit data to a website. there will be 2 input txt files in the following format: Input 1: Elephant#URLone Mouse#URLtwo Input 2: Mouse#TextDataA the app will read Input 2 from top to bottom and look for the corresponding URL from Input 1. from the example above, the app will read Mouse#TextDataA so it will open URLtwo and submit TextDataA in that URL. IMPORTANT: i will need someone who also knows how to handle proxies because i might need it to have proxy support later on in the future.
