It does not make sense to talk about taking a buffer out from a frame.
Buffers exist within the core of Emacs independently of any frames. A
buffer can be displayed in zero or more windows, and one or more
windows are part of a frame.

                      1 ┌───────┐
        ┌───────────────┤ Emacs ├────────────────┐
        │               └───────┘ 1              │
        │ 1..*                                   │ 0..*
    ┌───┴───┐      1..* ┌────────┐         1 ┌───┴────┐
    │ Frame ├───────────┤ Window ├───────────┤ Buffer │
    └───────┘ 1         └────────┘ 0..*      └────────┘

Therefore, you create a new frame, it automatically has a window, and
you arrange for that window to display your buffer. Optionally, you
bury the buffer in the original window so that it displays something
else, or delete the original window. (See code by Christopher in the
other reply.)
