arrays in awk???

Been struggling with a problem, I have been trying to do this in awk, but am unable to figure this out, I think arrays have to be used, but unsure how to accomplish this.

I have a input file that looks like this:

141;ny;y;g
789;ct;e;e
23;ny;n;u
45;nj;e;u
216;ny;y;u
7;ny;e;e
1456;ny;e;g
2;ct;n;e

I want the output to look like this:

ny: 141 23 216 7 1456
ct: 789 2
nj: 45


Is this possible? I know it is, but I can't figure it out, would like to use awk if possible.

thanks in advance.

Name
       tbl - format tables for nroff or *roff

Syntax
       tbl [files...]

Description
       The  preprocessor  is used for formatting tables for or The input files are copied to the standard output, except for lines between .TS and
       .TE command lines, which are assumed to describe tables and are reformatted.

Options
       -TX     Produces output without fractional line motions.  Use when the destination output device or printer or  post-filter  cannot  handle
	       fractional line motions.

       -ms     Reads in macros prior to table formatting.

       -mm     Reads in the macros prior to table formatting, if your system has the macros installed.

Examples
       As an example, letting 	 represent a tab (which should be typed as a genuine tab) the input

	      .TS
	      c s s
	      c c s
	      c c c
	      l n n.
	      Household Population
	      Town	Households
	      	Number	Size
	      Bedminster	789	3.26
	      Bernards Twp.	3087	3.74
	      Bernardsville	2018	3.30
	      Bound Brook	3425	3.04

	      Bernards Twp.    3087    3.74
	      Bernardsville    2018    3.30

	      Bridgewater      7897    3.81
	      Far Hills 	240    3.19

       If  no  arguments are given, reads the standard input, so it may be used as a filter.  When is used with or the command should be first, to
       minimize the volume of data passed through pipes.
