Selecting different values from different columns [closed]

I need a query to select different values from different columns as shown below:

timestamp          queues           queuesname        groupnumb
23-01-2014         FNG              CGI               15467P
24-02-2014         ACS              GHK               15467P
26-02-2014         ERT              FNG               15467P
01-03-2014         ACS              TYU               15467P
04-05-2014         TYI              GHK               15467P

I need the the row with queues = ACS (latest one has timestamp 01-03-2014) and queuesname = GHK (latest one has timestamp 04-05-2014)

For the above example I need this output:

Min_timestamp      max_timestamp       queues       queuesname    groupn
01-03-2014         04-05-2014          ACS          GHK           15467P

I don’t need a hard coded query.
