Folder SimpBurn is a tool which can burn folders to disc and create ISO images. All its options are on a single dialog which makes it very straightforward to use. At a minimum all you need to do is choose your optical drive, select a folder which you'd like to burn, click Burn Option > Start Burn, and then watch as your disc is created (CDs, DVDs and Blu-rays are supported, as single and multisession discs).
