Java linux中的SMTP/POP3客户端

我想在linux中开发一个STMP/POP3客户端（仅客户端）。我希望使用数字证书加密数据（我将尝试提供端到端安全性）。我还想创建一个简单的界面（带有文本字段、发送按钮、收件箱等）。我的问题是：我应该用java（如果可能的话）还是C/C++（在这种情况下，我必须为接口->QT使用一些工具）。你怎么认为？

还有我的第二个问题：如果您有任何想法/建议或有用的链接（或任何对我有帮助的链接），我将不胜感激。

关于您的第一个问题

我应该用java（如果可能的话）还是C/C做这件事++

你可以使用任何你觉得合适的语言，如果你想要我的建议，我建议你使用java，因为使用Swing或Javafx创建图形界面非常容易，而且有很多库可以帮助你实现目标

第二个问题呢

如果您有任何想法/建议或有用的链接

您可以在本网站上找到一个有用的教程，该教程将指导您从开始到结束：

下面是一个简单的应用程序界面，从使用JavaFx创建的项目开始

Main.java

EmailController.java

Email.fxml

谢谢您的意见！
