For Ifc-to-Obj, you should take a look at the Xbim framework (xbimteam on github) as you will be able to generate triangulated polyhedron and then turn it into OBJ data.

In all cases, without a framework for parsing your Ifc file, you won't be able to go anywhere ...

It is going to be hard in opposite Obj-to-Ifc direction, as OBJ format does not contains building element informations you'll need to create an Ifc.

Might come a bit late, and I know that it doesn't directly answer the question regarding the programming language, but if you have the possibility to use JavaScript/NodeJS, you could use the ifc-convert package based also on IfcOpenShell. It worked fine for me. Hope it helps.
