If you search for Microwave toolbox, Microstrip Calc is for you. It is easy to use, eyecandy calculator for microstrips, couplers/dividers, striplines and many others. For example you can calculate all impedances for your Wilkinson divider and write it into PC application (Ansoft Designer, Microwave Office...), without use complex equations.
