Implement URL BUTTON class

You might want to give more context on this question. What programming language do you want to use? Where are you going to stick the button? In a webpage, your own Win32 application, on the taskbar, on a pancake? What exactly do you want the button to do? Display a URL, download a URL, open the default application for handling the URL?

Sorry for that short info.

I want to subclass WC_BUTTON to make a Url button.
I just want it to have underlined text with different color. When I hover on it - the colour must change. When I click on it - default browser executes link (this part I have already implemented w/ ShellExecute() ).
This must be done with Win32 API, C/C++.
