In the Programming mode of gcalctool, you have a log button, which calculates the logarithm, but how do I know what base it's using and how do I change it?

For example, how would I calculate the base 2 logarithm for 16?

By default the log button calculates base-10 logarithms (while the "ln" button does, of course, base-e logarithms).

To specify a different base, you use a "subscript":

Type "log" in the input field.

Input your desired base with a subscript. This can be done either by clicking on the "downarrow-n" button (top left) and then entering the number, or by pressing Alt while typing the number.

Finally type the number whose logarithm you want to calculate.

By the way, I found this pretty easily by accessing gcalctool's help (press F1) and looking for logarithms in the index.
