In the year 2006, I had created a project as a part of my academics. I finally managed to find the source code and complete project report which I have uploaded to Github. Mainily, I have updated the source code to use cmake build tool. The project documentation is in Asciidoc. Although it is quite an old piece of code, it works:

plyloviz – Phylogenetic Trees Visualization
phyloviz: phyloviz is Phylogenetic Trees Visualization tool. For more details visit Generation and Visualization of Phylogenetic Trees.
Technologies: C, C++, Qt4, ClustalW 1.83, Coin3D, Bioinformatics
I hope it is useful for someone already working in the field of Bioinformatics / Computational Biology.
