Please show some attempt, so we can see what sort of difficulty you are having, and perhaps also figure out what the goal really is. That's also part of the reason for asking for more information about the context. We need to know, on one hand, that the problem is well-enough defined to be able to say it can be done, and on the other, what parts of the algebra you think you can't do.
When you say, "in terms of the A...I complex values", do you mean that these are complex numbers, or that you want the result only in terms of A through I without regard to how they are defined, or do you mean in terms of those other variables in terms of which they were given?
If I understand the goal, there are several ways you might approach it. One is to note that, for example, A/B appears several times, so you might first simplify A/B to (C/Q)^(g^2), and then substitute it into the given expression; and likewise with other fractions (though most don't work out as nicely -- so much so that I'd want to check whether everything you gave is correct). Another approach is to notice that many pairs of fractions have common factors in their denominators after substitution, so you might just substitute and find the LCD's.
In looking for things to do, I notice a couple issues I hadn't seen. One is that you appear to be using C in two different ways! Another is that the t's look almost as if they were function arguments, rather than being multiplied; I don't think you'd mean that, but I'd normally have written t_w * C^(g^2) rather than C^(g^2)(t_w).
