That doesn't matter; you can still use Visual Studio to create the .rc file. This technique still works great for MinGW-based projects. The important thing is that Visual Studio has a .rc dialog editor.
There are several .rc editors for Windows outside of VS that incorporate visual dialog editing. Pelles C would be one example that still gets regular updates.
Thanks for the tip about Pelles C. I just fired it up and it's a little clunky (so is Visual Studio) but I was able to load and edit a .rc dialog resource. Visual Studio's old dialog editor is pretty crashy these days so it's great to have an alternative.
