Two Simple Calculators in Java

Hi, I need two simple Calculators made in Java so they're compatible on multiple platforms. Example apps: Percent change: [login to view URL] Stock Calculator: [login to view URL] (doesn't need all the extra settings this one has) [login to view URL] General for each app: - Two separate apps. - Each app should have the same size window. Fairly small size window. - In Preferences menu.: Font size of the application text and the input/output text should be adjustable separately. - When clicking in the input fields the text should automatically select all on first click and then allow cursor placement on second click for editing. - Can TAB to the next line. On TAB to the next line, if there was already text there, select all is applied to easily type new text. - Hitting ENTER submits the form/calculation. Specific to Percent Change app: - In Preferences menu.: Option to select how many decimals are displayed in output calculation. Input fields can use what ever the user inputs. 1 and 1.1 or 1 or 1.11 or 1 and 1.111 and other combinations should all work. (If the input must be updated so both fields use the same amount of decimals that is fine but the user can't need to input them, they would need to be changed automatically when TAB'ing or focusing off the input field. It needs to be very simple and fast.) - Output calculation uses same font size as input text. The rest of the application text is separate. (Like shown in example app.) - Do not need the extra settings on the left of the first example app or the extra buttons on the right. Also don't need the graphical indications that are shown in the second example. Specific to Stock Calculator app: - In Preferences menu.: Setting to choose which toggle is set by default in buy section. - Sell section is collapsible, making the window smaller. - Do not need the commission, tax portion or explanation of calculations as is shown in the example app. I will provide a mockup of the apps so you can see more clearly. Working on it now.. This is a very simple project so I expect it cheap. Around $50, not more. Please make sure in your bid text to include "DDD" so I know you actually read the post. Thank you
