Actually, there was a witch in the cartoon. If I remember correctly, we see her for a few seconds waving from a window overlooking the parade.

The figure you site is in silhoutte in the forground. While the profile wears a pointed hat with a broad brim and has a pointed nose, this is really not a witch, but a citizen of The Emerald City. The pointed hat was worn mostly by the Muchkins according to the original W.W. Denslow illustrations. This was carried over as a design element for this character. As important as the Wicked Witch is to the story, again, she is absent from the 1933 cartoon.
As for who "wrote" the story for the cartoon, that is vague since the credits site "Colonel" Frank Baum for the story. This is odd since Baum attended a military school and was discharged at age 12 for a heart condition. For this reason, he never served in the United States Army as a grown man, so the reference to him as "Colonel" is puzzling. But the "story" as it is, is a very skeletal version of Baum's book, using only 3/4 of the main characters, and is missing much of charm and witty dialog, as well and the dramatic contrasts. I suspect that the animators took a free interpretation since there really is no story structure per se, but merely a series of scenes set in a pedestrian fashion.
On another note, it's interesting to see Carl Stalling credited for the music, some of which he reused in PORKY IN WACKYLAND. Other credits refer to "Drawn by" Frank Tipper, Cal Dalton, Bill Mason, Vet Anderson, and "Hutch."
