For my own future reference :)
First off, prefix all these with sudo, because the site-packages under each installation of python is protected space.
First, install pip for python3:
apt install python3-pip
Then install wxPython:
sudo pip3 install -U -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-16.04 wxPython
Then in the dabo folder
sudo python3.7 setup.py install

And now I have my own copy of dabo, which at least loads. We'll see how this goes on.
