If you want to harness the power of Ghidra decompiler but without the need of installing Java - Rizin[1][2] and Cutter[3][4] (Rizin's Qt GUI) integrate Ghidra's decompiler part that is written in C++ (libdecomp) as plugin - rz-ghidra[5]. We work currently on improving the integration and the quality of output.
