Not sure what you're asking, including what
you mean by "different desktop environments".

I've long had commands that let you resize or
move frames around incrementally (e.g. by
holding down a key).

You can certainly move them across different
_monitors_.  I don't see how Emacs desktops
would be related to frame movements, but
perhaps you mean different platforms?

Anyway, in case it helps: see frame-cmds.el:

https://www.emacswiki.org/emacs/download/frame-cmds.el

Some suggested key bindings:

* `M-up|down|left|right': move frames around incrementally.
* `C-S-v', `M-S-v', `C-S-next', `C-S-prior': move frames
    to screen edges.
* `C-M-up|down|left|right': resize frames incrementally.
* `C-x {', `C-x }', `C-x ^', `C-u C-x ^': resize windows
    incrementally.
* `C-M-z' or `C-x C-z': iconify/hide all frames.
* `C-M-z' in a lone frame: restore all frames.
* `C-mouse-1' in the minibuffer: restore all frames.
* `C-mouse-1' in Dired: mark/unmark a file.
* `C-mouse-3' on the mode line: remove window from frame.
* `tile-frames-horizontally', `-vertically': tile frames.
* `C-x o': select `other-window' or `other-frame'.

Maybe `move-frame-up' (`M-up') etc. are
similar to what you want to do?  But there's
no "base frame" and "presentation frame" -
you directly move a frame (default: selected
frame) incrementally by holding down a key.

frame-cmds.el requires frame-fns.el:

Other frame-command libraries:

`autofit-frame.el' - Automatically fit each frame to its
                     selected window.  Uses `fit-frame.el'.
`fit-frame.el'     - 1) Fit a frame to its selected window.
                     2) Incrementally resize a frame.
`doremi-frm.el'    - Incrementally adjust frame properties
                     using arrow keys and/or mouse wheel.
`thumb-frm.el'     - Shrink frames to a thumbnail size and
                     restore them again.
`zoom-frm.el'      - Zoom a frame or buffer, so its text
                     appears larger or smaller.
