The Two-Layered GUI Toolkit is a library of GUI helper classes which is designed in a way to simplify development of separate interchangeable front-ends. For every supported dialog box type, there is a settings class (independent from a GUI toolkit) whose options can be used by one of the implementations for a specific GUI toolkit (bindings for Gtk#, WPF, and WinForms are provided, but custom ones can be added). That is, the dialog definition can be prepared by the application's core component and passed to the front-end, which uses it to instantiate the dialog box using whatever GUI toolkit it likes.
Rescatux is a GNU/Linux rescue CD that comes with Rescapp, a nice wizard that will guide you through your rescue tasks. It can restore Grub to the MBR update a Grub configuration, perform filesystem checks, fix a Windows MBR, and more. Features that can indirectly assist the rescue process include chat programs to let you reach human online help, a share log (automatic pastebin), and a share log that uses formatting appropriate for posting on a forum.
