I use gimp to create / arrange the images and stuff, but paintbrush or any editor would work depending on how complex you want to be. I use gimp because of the layers but I am far from proficient. I paste the finished image into MS Word for printing. I only use Word because I made a sort of template that is the exact size of each label paper I use (6 per page). Copy -> Paste -> print. I use the same label process for wine & beer labels.
