I didn’t find out about this amazing IDE until I was browsing for themes for my KDE 4 desktop on kdelook.org and saw an interesting looking icon in one of the theme screenshots. Curious, I googled the icon name (qtcreator) and was pleasantly surprised to find out that it was Trolltech’s own IDE for Qt.
It’s amazing. Really easy to make anywhere from quick and simple GUIs to complete and complex applications. The source editor is really cool too. The IDE looks nice, loads fast, feels slick and is available for Linux, Windows and Mac. Completely free.
