How can I retweet the same message on multiple Twitter accounts simultaneously?

[Stunned & Hurt]

For example, my company has multiple twitter accounts. I would like a program for a PC that can manage the multiple accounts allowing me to create one message to retweet to my other accounts simultaneously.
I would appreciate any and all suggestions.

Use a Twitter Client such as Seesmic, CoTweet or Hootsuite. My personal favourtie is Seesmic as it is free to use. Alternatively you could employ a social media management service to manage your Twitter accounts for you.
