OpenGL is just a standard. The actual implementation of the API is up to the graphics card manufacturer. So yes, OpenGL development can be GPU dependant sometimes. However, all implementations should provide the same result (what happens behind the scenes can be really different). If your code gives a different result with different GPUs, there is probably a version difference in the OpenGL implementation.

You can use these functions to get the supported OpenGL version:

glGetIntegerv​(GL_MAJOR_VERSION​, *); //version 3.0+
glGetIntegerv​(GL_MINOR_VERSION​, *); //version 3.0+
glGetString​(GL_VERSION​); //all versions
