I've seen references to a libgdb project.

An idea left over from ancient days, never got off the ground. The theory was that one could link it into both the traditional command-line frontend and into various GUIs. Lots of technical difficulties, two chief ones being that 1) it would have had to be a very "wide" API in order to be sufficient to cover all of GDB functionality, and 2) the library would have to be able to hand control back to the UI on demand, difficult when inferior control uses blocking system calls. In practice, it seems to work well enough to have the GUI be a separate program that communicates with GDB, whether via command line or MI (machine interface) syntax, and there is some advantage to the "firewalling" inherent in a two-program scheme, so there's not much motivation to do a libgdb anymore.
