WiX is great in that there is no GUI, you just write the installer you want it to be. No fiddling with GUI-wizards!
However, drawing GUI is actually one thing I prefer to use a GUI for.
So, is there any Dialog-drawing program which exports WiX-data?
(I suppose else-wise perhaps I could transform what Visual Studio's forms editor does to WiX-XML.)

SharpDevelop also has built-in capabilities for laying out a WiX dialog. I prefer it over WixEdit.
I created a full list of editors for WiX here: http://robmensching.com/blog/posts/2007/11/20/WiX-editors (which is amazingly still up to date)
If you use Visual Studio 2008/2010 and want to install an application that requires .NET framework you might be interested in having a look at SharpSetup. It allows you to graphically edit installer UI as WinForms controls (and use VS designer for that).
Sharpsetup blew up in my VS 2010 with the message: "HRESULT E_FAIL has been returned from a call to a COM component". It didn't finish the "Assembler"-project, and the setup could not be used.
