Is c++ good for designing a mixture of 2D and 3D application?

I would like to design an app that contains a 2D GUI for performing general purpose tasks like project creation etc. While most of it is 2D, some part, say one window, contains 3D objects. I would like to find out if c++ is a good way to go for designing such an application. I know there are many ways of designing a 2D application. I can locally create a browser based application but I am not sure if it's a good soultion for such a problem. The 3D part of the application might get intensive at times. For example, if there are hundreds of object in the same window which can be manipulated individually or in groups by selecting. I have used java for 2D and can design python based apps but I am looking for a solution that can give the best solution? ( I know it's always difficult to find the best solution). I have seen some similar apps which are in c++. Is c++ a good way to go for designing such applications. I would also like to embed web based windows in the GUI at some point.

PS: I am looking for a cross-platform open-source solution. I work mostly on linux so getting something to work on it is priority.

Thanks
