If you're looking for a slow flyer, with docile roll rate, then Hankg's plan is in the ball park.
When I started to design and build my own planes I discovered the attached document. Very helpful. Author unknown. It's full of percents and ratios. The design of your wing is the starting point for the rest of the calculations. You start by determining how wide you want your wing to be then go from there.
Very interesting and easy to work with the ratios and percents on graph paper. I created several successful designs based on these ratios and percents. After that I started to take these figures and experiment.
See if the attached might be of interest to you.
