GUI Help

[seh1]

Hi,
I wrote the following GUI. Its total crap but just need to get the basics working first. Its compiles fine and my Hello World test message comes up but no sign of the UI itself. Any ideas at all ?
Much Thanks,
Sean

You simply forgot to set your frame visible.

try:

taxi.setVisible(true);

This isn't related to your question, but you're mixing AWT and Swing visual components. That is a bad idea in general. Please read the following artical for an explanation. http://java.sun.com/products/jfc/tsc/articles/mixing/
