I don't see anything Raspberry Pi specific in your errors. I think you should be able to do most of your design on a PC machine.

But pyuic5 creates code that doesn't add import Qwt and adds wrong "import qwt_xxx" lines. It needs to be edited. from PyQt5 import uic
QT SETUP
DesignerFile = "QWTwidgetTest.ui" app = QApplication(sys.argv) Ui_MainWindow, QtBaseClass = uic.loadUiType(DesignerFile) ui = UiMainWindow() window = QMainWindow() ui.setupUi(window) window.show() sys.exit(app.exec()) I don't think you can use the dynamic loading of the .ui files. You need to create the .py files, edit and import them.
Using the pyuic5 program in the following way fixes your problem, at least on Linux and systems containing grep and sed.
pyuic5 uifile.ui |grep -v "from qwt_" | sed 's/# WARNING! All changes made in this file will be lost!/from PyQt5.Qwt import */g' > ui_uifile.py
This will remove all "import qwt_" lines from your .py file and add "from PyQt5.Qwt import *" at the top of the file.
