I actually will chime in and say I use Wordpad more than anything else. I have only a couple of apps with a traditional GUI, most are web apps. There are web-developemnt tools out there, but I'm such a control freak, I can't stand to use any HTML-generator. Because you can usually tell the difference, in cleanliness, stability, maintainability, and performance.

Of course, now that I use Python a lot, I am using the "IDE" included with Python, which doesn't do much more than window and syntax-highlight.
