Design broadband matching network for amp - beginner

Hi,
I am a beginner to RF design, but I want to know where to start when designing a broadband impedance matching network.
I want to make 1W FM amplifier 88-108MHz using RD01MUS1 mosfet. I have the s-parameters, so what are the calculations I need to make a matching network. What type of matching network can be best used in this situation?
(If it is not obvious, I want to match both the input and output of this amplifier to 50ohms.)
If you could recommend cheap/free software that can do this I would appreciate. It seems like most people use Microwave Office, but I can't find an easy download for it.
If you can give me a very detailed description with the calculations -> values for the components, I will offer you a monetary reward.
Here is the s-parameter for 100MHz:
S11:
(mag) 0.945 (angle) -72.3
S21:
(mag) 19.517 (angle) 135.2
S12:
(mag) 0.039 (angle) 44.5
S22:
(mag) 0.742 (angle) -57.4
Thanks in advance.
