So How Do you Build a Desktop Application?

I see so many tutorials and guides for making websites that it's easy to see the process, but I'm at a loss for how to make desktop applications. What languages can be used? Are there frameworks for desktop apps? Are there guides online? Do you just use the same stuff for web app design now? I have no idea ....

For c# you can use old Windows Forms, or newer technology WPF.
Framework provides you with main form to which you can add controls (there are some predefined controls but for more complex requirements you can create your own).
It is actually very easy to start, you can create empty desktop app from project template, without writing single line of code.
