Taking cuttings from any type of pear tree is possible. Look up "pear tree propagation" to learn how to proceed. However, after reading all of the problems caused by Bradford pear trees, I would not suggest doing that. They are now considered an invasive species that are killing out other good trees. Cross-pollination with regular pear trees is also a problem. Given their relatively short life and weak wood that is prone to breaking in windy weather, please consider planting another type of tree.
