There are two ways to create a quick bibliography.
Zotero has plugins that allow you to write and cite at the same time in Microsoft Word and some open source word processors.
Directions on how to use these plugins are on the Zotero website and are quite good. Most screenshots below are using a Mac and Word for Mac 2011. Other versions may look slightly different.
Zotero Word Processor Plugin Options
Mac/Word 2011 - Find Zotero options under the Scroll icon.
Windows/Word 2010 - Find Zotero options on the Add-Ins tab.
You can add or edit a bibliography, add or edit a citation, set document preferences (i.e. select or change your citation style), and remove field codes (i.e. make the document fresh and clean to send to anyone else.)
Add a Citation
Search for your citation, then press enter. Voila! Citation added and formatted correctly.
You can even add page numbers to your in-text citation, suppress the author from the in-text citation if it makes sense, or add prefix/suffix information.
Add a Bibliography
Once you have finished writing your paper and inserting citation, you can add a bibliography to your text. Simply place your cursor in the text where you want the bibliography to appear, then select "Add Bibliography."
And then your bibliography will appear wherever your cursor is.
