Hi!

I am a beginner and I am learning to program on my spare time. I am working with a website to have a goal with learning Java instead of just making small programs... I have written lots of the code for handling input and publishing stuff on the website. Now I have come to the graphical part and I am stuck...

My idea is to have an applet with a text area. There is going to be a lot of buttons around the window. And when you push a button text will be published in the text area. My idea is to use JLabel to publish the text because then I can read HTML files and publish the HTML code directly.

However, I do not understand really how JLabels work. I have tried with "setBounds(0,100,600,800)" in order to change the size and position of the JLabel and in some way that works but not fully. Instead the program will publish the JLabel in the center of the applet. When I click the button more JLabels are published but nothing happens in the text area. Really grateful if someone could help me because I am really stuck and I don't have anyone else to ask for advice...

You can view the applet [HERE]...
