You need a language to receive the data from Wialon Retranslator or FLESPI. I'd recommend either ASP.NET or PHP. They are both decent web-programming languages.
In order to run these services you need a web-server. There are a lot of web-servers out there. The most popular and easy to use is probably Apache / httpd. Available as LAMP (Linux) or WAMP (Windows) Nginx can also be recommended - but is a bit difficult to work with.
If you are using SOAP as a protocol then it would send directly to port 80 to your webserver you can easily convert XML to JSON with built in functions in .NET or PHP.
