Wouldn't this command do what you want?
CAT1(config-if)#wrr-queue bandwidth 35 15 45 5
Flannagan, Froom and Turek give the formula for WRR bandwidth as below:
(W/S) * B = n
Where W is the weight, S is the sum of all the weights, B is the link
bandwidth, and n is the allocated bandwidth. In your case, the individual
weights add to 100 (%), so 35/100 * 100Mbps = 35 Mbps for Q1, Etc.
