First off, this is probably not the right section, but the question is asking which language I should choose... so I don't know which forum topic it should go under...
I am looking for a solution which would allow someone using an online panel running on my web server to connect with a Windows application that someone else may be running. Think of it as a chat system where someone would be able to go online and send a message to someone using the desktop client.
So my questions are;
How can I connect a web server to a Windows application.
How can I make the Windows application update once a new chat message is sent from the online panel (and vice versa).
Which languages would be capable of this?
Links to external sources/explanations would be great.
