Cut [?] , {?} From Columns B & C And Paste Into DEFG

i have a large wordlist containing Columns A, B and C. Now i have to cut and paste parts of B and C and paste them into DEFG. The content which hast to be cut and pasted has always the form "[?]"; "{}" or "{?". Now all "[?]" from Column B has to be cut and pasted into Column D and the remaining whole content of column B (can be "{?}" or withouth {}) has to be pasted into Column E. The content in Column E should be bounded by {} if not already there.

And all "[?]" from Column C has to be cut and pasted into Column F. And all "{?}" from C has to be cut and pasted into Column G. In some entries of C "}" is missing. In that case "{?" has to be cut and pasted into G.

For example:

A---------B----------------C
w1------[a]{n.}---------m1[aa]{n.m.
w2------{n.}[p]---------m2[aa]{n.m.}
w3------[q]ajsk----------m3{n.m.
w4------ead-------------[aa]{n.m.}m4
w5-----------------------m5[aa]

has to look like(Coulmn B will get totally empty):

A----------B---------C---------D---------E---------F------G
w1------------------m1-------[a]--------{n.}-----[aa]-----{n.m.
w2------------------m2-------[p]--------{n.}-----[aa]-----{n.m.}
w3------------------m3-------[q]--------{ajsk}------------{n.m.
w4------------------m4------------------{ead}----[aa]----{n.m.}
w5------------------m5----------------------------[aa]-------------
