Help making watchface

Hi all,

I have never done any coding and thought I could teach myself to do this and make a custom watchface for my wife's birthday. But seems like I overestimated my own abilities :)
So could any of you help?

Would like to make a watch face, square, digital, can be quite similar to the default for 920xt.
But would like to have my wife's name or initials in upper left corner, followed by a heart.
Top right corner: a battery percentage.
Bottom: date

If anyone could help out I would be very happy. But understand if it is too much work.
Was hoping someone could share the .mc "code/text" so I could maybe tune the font type and sizes myself, if that is feasible for a noob.

Or any other advice is appreciated, like an indepth guide on how to do it.

Cheers!
