For one digit:

 \kx\D'c 1.5'\h'|\nx'  \v'.25m'1\v'-.25m'

 \kx\D'c 1.5'\h'|\nx' \v'.25m'10\v'-.25m'

PIC

 .de bun
   .\" arg1 - number
   .\" arg2 - color
   .PS
     .sp -2.4
     move left 4.0
     circle radius 0.1 "\s-2\fB\m[white]\\$1\m[black]\f[]\s+2" shaded "\\$2" outline "\\$2"
   .PE
 ..

Example

 .bun 1 red
 .bun 2 blue

Caveats:

PIC Images are placed in the middle of the page. The macro tries to circumvent this but doesn't do to correctly.
