General comment: you're putting the cart before the horse. Those who follow such a horse only see a horses behind that is going nowhere.

Bug tracking software like Bugzilla is a tool used to manage the process of identifying, tracking down, and fixing bugs. Solid experience with managing the process of identifying, tracking down, and fixing software bugs in a team environment is an essential prerequisite for designing and writing any useful bug tracking software.

If you're only slightly familiar with C++ and Java, you probably have only had a little bit of practice with programming. A little bit of practice with programming means you have very little experience with identifying, tracking down, or fixing software bugs in relatively small software configuration items. You will need quite a bit of practice with systematically identifying, tracking down, and fixing software bugs before you will even have a hope of managing a team going through such processes. Once you have some significant experience with managing a team though such processes, you will have enough useful knowledge to begin the process of designing tools to help manage the process.

Until you have those sorts of experience, I suggest you suck in your pride, and use tools like Bugzilla. They may seem painful but, until you have solid experience, you will not be in a position to identify what features of Bugzilla software cause you pain for a good reason (ie the authors of Bugzilla know something you don't) and what features are candidates for improvement.
