   Here's a SlimDX (MDX) GUI
  If you need a GUI for SlimDX you can have a copy of mine, under the MIT license, source code and all.  You can download it from:http://www.jldoty.com/geek/mdx_gui/MDX_GUI.htmlIt's fairly extensive and includes check boxes. radio buttons, radio button groups, edit boxes, command buttons, drop-down combo boxes, list boxes, static text, modal dialogs, dragable dialogs, sliders, tab controls, tabbed page controls, tools for customizing the GUI.I use MDX to do some 3D modeling, but since Microsoft stopped supporting MDX after the August 2007 release of their DirectX SDK, I've had one foot stuck in August 2007.  I openly acknowledge that I started with the GUI in that release, but since then I've made extensive modifications to it.  I've corrected a number of bugs, eliminated a lot of undesirable features, and added quite a number of features it originally did not include.Recently I began porting all my MDX apps over to SlimDX, so if anyone wants the GUI it's yours.Some things I still need to do are:1. port tab controls and tabbed page controls to SlimDX 2. comment source code more extensively 3. provide some documentation to supplement the demo and comments in the source 4. test it properly in RELEASE mode.If there's enough interest I'll accelerate work on the above list.  Otherwise, I'll take my time.
