So that would mean I would have another layer in my design which I would call FPGA bus. Thats not that bad, but it also means I would have to make the FPGA blocks in a way they can be connected to that bus, right?

You would design your components with "standardized interfaces". Unfortunately, there are several standards, so you have to decide whether to choose one, or multiple.

Or could there be a possibility there already are the blocks to integrate the AXI standard?

AXI is one of the standards that both Altera and Xilinx support. Using this standard should make supporting both vendors easier - even if the internal implementation had to have some vendor-specific logic.

I want to do all the work for the user, so that the user has its compiled image and can just push a button I made in my interface and it will be programmed in it. I am just not aware if it is possible to make such a thing, or if I would have to start quartus for example and let the user push the program button there.

It depends on how you design your hardware. Its very easy to load binary configurations created by Quartus at a later point in time.
For example, the FPGAs on +100 of these boards are dynamically reconfigured
http://www.ovro.caltech.edu/~dwh/carma_board/ without ever using Quartus. Quartus is used to create the configuration images, but then they are stored on a filesystem for use when the FPGAs are to be reconfigured.
