Yes! I just created my first successful webapp on #UbuntuTouch (to access my Desjardins credit union account) using the webapp creator from the OpenStore. The simple webapp option didn't work, I used the Ogra alternative and that worked. What helps is that the website is in responsive design and is phone-friendly. Maybe I'll upload it to the OpenStore, although there are probably not many Desjardins members using UT.
