Being of the "I am not programmer" group as well I use the following process:
Use MyPhoneExplorer (MPE) to copy the full ODK directory to the desktop. I use MPE since windows does not seem to recognise or copy over all XML files. JPG's are fine.
Then to pull forms use 'Custom Path to ODK Directory' from the 'Pull Data From' dropdown menu in Briefcase and navigate to your copied ODK folder. Just select the folder not the contents.
Then pull the forms you need into the ODK Briefcase Storage folder.
I then export my instances to a dedicated output folder.
Note. I have to clear the files from the ODK Briefcase Storage folder before I download a new project. Otherwise it will concatenate your old data to the new. I also delete the downloaded ODK folder on the PC once I am happy with the result and remove the instances from the device.
MyPhoneExplorer should be installed on your PC and your android device to work and have developer mode enabled with USB debugging checked on your android device.
The hardest part is probably getting MPE to connect. Once you have that working the process is easy if not a little convoluted.
