Welcome to the forum. If I were you, I'd try to watch and read as many plays as I could. And TV dramas, films, novels, short stories. Maybe your local library has famous plays on record? It's a long shot, but maybe worth asking. What about your theatre company? Don't they have a stock of plays, from previous productions? The more information and technique you absorb, the easier the writing. In theory anyway.
Check out the
playwriting prompts / tips thread in Playwriting forum which has a couple of interesting links.
And the
Getting in to playwriting/screenwriting thread in Script Writing forum.
If you're really truly stuck for ideas, try
http://www.seventhsanctum.com/index-writ.php
which has story generators galore. Just as a crazy example:
"This is a comedy-of-manners. The story is about an odd champion, a performance artist, a reporter, and an inventor. It starts in a space launch facility. The critical element of the story is a betrayal. The gap between the rich and the poor nations plays a major role in this story."
Hey, I said it was crazy. But you never know when something crazy can give you an idea for a story.

Take the critiques you get with a grain of salt. Invariably, some of the critics will be kooks, bitter curmudgeons, or complete fools. ~odocoileus
