You can do, it's just a panel with borders. A round robin. One step at at time!
It's really the fabrics in this case that makes the quilt.
I'd probably start by doing all those little quarter square units as warm up and what I call "Front Loading" getting the time consuming repetitive tasks done before the fun of putting together the top.
I made a QST recently and I use tape on my rulers to help me with my vision/consistency issues. I had precut squares that varied between 6-6.5", cut them on a diagonal, and then trimmed them down to a consistent 7.5" (non-standard ruler) square. The tape line is the diagonal mark between the 7.5" marks on the sides. I use that and the printed line on the ruler to make my QST square quick and exact.
