Need to develop UI based debugger tool for c++ code matinaed in unix platform [closed]

I am working in c++ code that is developed and maintained in unix.

I need to develop a UI based debugger something like visual studio which will help me in faster debugging and provides all information like stack frame, watch etc.

We currently have GDB to debug code in unix, but it is not developer friendly.

So I am looking for some open source upon which I can have some add-on to have a debugger with good UI and that will help me greatly in understanding the code flow as well.
