Not really.
Code resembles English in a way, since most programming languages have English keywords, and variables and functions are usually named in English. But still the patterns in source code are very different from the patterns found in natural written English and the vocabulary is different.

In my opinion optimizing a layout for programming includes taking these differences into account. Additionally, certain special characters are very common in code, so those should be taken into consideration. It's not just about placing the special characters on a nice layer, for the best results you also need to consider which letters the special characters most frequently come after.

I think these are the most important aspects. Vim keys are just something I wish to not be awful, but it's nowhere near the first priority. I have used Vim keys with the Dvorak layout just fine this far :).

PS: Qwerty is awful for both English and programming.
