I personally think since you have admitted to making only one quilt, and you do not want to invest in excessive tools, templates, etc., you would be better off staying with either squares, rectangles, or the like....no additional cost there presuming you already have at least one ruler, a rotary cutter and mat. So I suggest you find one of the more modern patterns which do not require a lot of "work" and by picking the fabric you want, will fit your criteria.....
