g1=Simplify[D[f,t]/f];
g2=Simplify[Integrate[g1,t]];

your question begs the question if all integrals can be assumed solved
using some method: no.  but...

the above seems to only depend on whether g1 has a proper derivative ,
and if that is so you can use Log directly (knowning that's the
answer) rather than integrate, right?
