Scientific Workplace is simply the best WYSIWYG latex software under windows, especially for new latex users. It hides all latex complexities under its GUI interface and provide shortcuts for all common symbols. With the help of menus, toolbars, especially keyboard shortcuts, inputing math formula is really easy. A notable feature of SWP is that you can name and save any fragment of text or formula so that you can use it later by its name.
Scientific Workplace, like most software packages are available to rice graduate students for free.
WinEdit is another latex software under windows. It is not WYSIWYG.
It displays plain latex file and it will insert \alpha
if you click `
from the toolbar. Many experienced latex users
like WinEdit since they can make use of toolbars, menus, shortcuts
to speed up inputs and have full control of latex source code as well.
Both software are not Rice supported and you have to buy them yourself. (I heard that Rice will have site licenses for SWP.)
