I assume you refer to the black walnut, which is the only species that will do well in most of our state. Collect the walnuts when fully ripe and sow them in a box of moist sand or peat. Usually, fully ripe nuts will fall to the ground for easy harvest. A few inches of mulch over the seed bed will protect the seeds from heaving.

Hot peppers seem to be gaining more and more aficionados.
I can't take them too hot, but I have plenty of friends who will go to great lengths to get the hottest peppers around. The best way to get the hottest fruit is to plant the hottest cultivars you can get your hands on, assuming they will ripen in your area. Spanish researchers reported that peppers of the cultivar 'Padron' were significantly hotter, or more pungent as we scientists like to say, when the plants were drought-stressed. Now this stands to reason. Grapevines that are stressed product more flavorful wines, and many other fruit, when shy on water, develop more intense flavors.
