Graphical designers

Ubuntu makes available a rich set of user interface elements in the form of widgets: reusable UI blocks that you can combine to easily build usable and extensible interfaces to enable users to interact with your app. While all widgets can be combined and written with code, GUI designers are the tools that facilitate building these interfaces in a visual way. With them, you can arrange widgets, drag and drop them and do anything you would expect from a WYSIWYG editor and rapid-prototype functional UIs in almost no time.
