max/msp programming

Hi there , ive been working with max/msp and processing the last few years but have never got to the point of needing to create a full standalone application combining them.
Basically, im trying to create an application in xcode that will open a .app file, .java, or .pde file (processing exports), and also to open a .app file (max/msp export).
Im very new to this, so any help would be hugely appreciated
Thanks
