How to make a right-click translation dictionary application?

I'm trying to write a dictionay application on C#. There is a scenarios that user selects a text and press a hot-key, I want to pop-up a quick windows that display the search result of the selected word (just like Lingoes does开发者_如何学编程)

How would I do it in C#?

Thanks in advance

Start with Google this:

• hooks, global hotkeys (for monitoring global keyboard and mouse events)
• WinAPI (to do such tricks as grab any selected text)
