414835 Windows App with File Transfer

We need a small Programm that easlily installes themself as a desktop icon on Windows (XP, Vista, 7) Whenever a Document is draged and droped on that icon a small input field is being shown and the user has to insert a faxnumber. That document is being transfered via XML-SOAP Gateway to our server (https) including the faxnumber and the username/password out othe the settings menu. The programm needs to have a very small settings menu (maybe the menu opens after just double clicking the icon, without drag & dropping?!). Within the setting the user can insert its username and password, and two other fields with a name and a phonenumber (which is used as the sender information). That programm need to have a language file as it will be available in english and german in the first place. (Translations into german will be done by ourselfs) In general. After transmitting the file to the server, the server will return an answer (error or ok with some text information in the status) instantly as answer on that request. That info needs to be shown to the user instantly as well.
